[imtheone]

this is the first time ive posted in a forum before so bear with me.

so i meet this girl on a dating app in june,i am 28 she is 21 we were texting and flirting for a week or two, we had so much in common and was comfortable with each other.

during those two weeks of texts was playing it cool and this seemed to make her desire for me to increase, she would ask to hang out and come round mine, i was telling her no its too soon to come round mine, this would make her desire to see me more, even suggesting getting the train and wait for me after work, keen right? then one early staurday morning i get texts saying why you flirting with my gf, so i called the number back and some guy basically said her girlfriend is texting me while she is in a relationship, to which i say its not my thoight she approached me on the app and asked for my number and keeps asking for a meet, anyway after a few days i talk to the girl about what the hell was that about she told me she is with someone but its fading thats why she is contacting me and that, Anyway i finally meet her after another few days , picked her up and we just talked in my car about her situation and general stuff, we even started kissing and i had her top off in the backseat of my car, but we didnt have sex. after we start texting as usual, then weekend comes and shes distant, i suspect now shes with her ex cause her ex lives an hour or so away and she said before she used to stay round his weekends, cause they didnt see each other in the week, i bring it up but she denys it, ok fine so we carry on talking and see each other the next week, hang out a couple of times and she even slept round mine, but we didnt have sex just kissing, touching etc. couple of days later she goes back to her hometown (hong kong)(we're chinese) for two weeks,(we are from uk btw) we text but not as often cause of time difference, during that time she would say i dont care about her cause i dont text her and that and she says she misses me. anyway she comes back to uk for 10 days, we see each other 7 out of those 10 days, she tells me she loves me during that time and we have sex, i dont love her at this point cause im still thinking if she has her ex on the side still so i just go along with everything taking it slow, then she brings up about being in a relationship cause she goes back to hong kong for 5 more weeks for the summer so she dont want me dating other people, so i agree and we are a couple, shes away for those 5 weeks, we text everyday and talk over the phone 3-4 times a week, in which we grew so close together, towards the end of the trip i start to fall for her bad, but then she goes a bit cold, not answering my calls, texts are a bit more blunt and so on, i expect theres something going on with her ex still as she did say they stay in contact, i feel like im losing her so i sent a silly dramatic text pouring my heart out, which i regret now, she replies i think we should stay friends, i flip this and say i actually agree(which i didnt) and its fading out, and we should meet up face to face to clear the air and go our separate ways, she agrees to come for dinner but asks me if were getting the new iphone together as we agreed we would before, i say yes thats fine, but is that her way of not letting me go after i say we should go seprate ways? anyway shes back home we go out that night, and agree to be friends, everything is chilled and more relaxed than before, she starts bumping into me when we walk side by side, think thats her way of getting close to me, so we go back to my car and talk for a bit before i take her home, we kiss, and touch each other for a bit before we leave, i see her a few days later and its the same, a nice night with a bit of groping etc, then weekend comes and she says some stuff about doing housework, which i know is lies cause shes most likely seeing her ex.

we agree to meet the following week, but she flakes on the day saying shes ill and i say thats cool we'll see each other another time, we text flirt but things are different just not the same anymore i can feel it, then she gets my phone and i have to pick it up from her house, i go see her and she just pops her head out the door and says here you go, and that was it! again we text as usual but nothing much more, i dont ask her out again cause she flaked before and if she wanted to see me again she would make her feelings clear right? she never, so i guess i know where i stand, we text all the time but she never mentions she is taken or anything and just acts single, she just says she does stuff with family even when i know shes seeing him. anway a couple of weeks later i see she post photos of him and her on social media, im not on facebook, so she knows i couldnt see what she posts, but my friend has and was curious to see what she was upto so searched her to find that picture, dont get me wrong i knew she was seeing him, so i accepted that but i just felt a punch to the gut seeing the photo myself. i really dont know what to do! i know she has something there with him cause they have been together since january so they must have built a connection over that time and made memories, but i just cant seem to stop contacting her even though im seeing other people also, i tell her about me dating and stuff but she never says anything about her situation. why dont she? is she making herself available? its so confusing. part of me wants to forget her and just focus on my life, but another part wants me to pursue her and see where it goes, but i dont want to be caught in a love triangle, cause eventually someone will get hurt, and it will mostly be me. sorry if this post is so long, i just wanted to give you an idea of where im at at the moment.
