I think I'm obsessed with my girlfriend's ex gf.

[LoveCautionly]

This is going to be long considering its a messy situation. I honestly don't know what's wrong with me to act like this but I just can't help this. Obviously I'm gay/bisexual from the title. I've only dated two girls my whole life. I dated a girl for a year and left her for another because the other treated me so much like I wanted and deserved. I normally don't ask for a lot in a person just to be trustworthy and faithful. I'm a straight a student and I try hard in everything I do including my relationship. Anyways, I've been with my current fiancé for a year and a half. I'm truly in love with her and wouldn't trade this type of love for anything. Her ex girlfriend of four years was in the picture for the first month or so because I let them talk until I felt comfortable enough to tell my fiancé to stop talking to her because she's Nothing but trouble and drama. Every chance the girl gets to start crap she does. She got on topix this site where others talk crap about others and ran her mouth to me when the post wasn't any of her concern whatsoever. About a month after that she comments on my fiancé's bestfriends picture which is also her friend and mine and said " ____ always loved baby's!<3 " because it was a picture of my fiancé holding her best friends baby girl. Of course I instantly got red in the face and wanted to go through the computer screen. This all happend on Facebook. I commented below and said some stuff to make her jealous like oh my fiancé's beautiful with her bestfriends baby. I made my fiancé go unblock her ex and comment down below just so she could see it and It'd piss her off because she wrote back to me and said sweet stuff. After all this she sends my girl a message saying I miss you and I don't want no trouble and said she was coming to my fiancé's moms house to see her family and all that bull crap. My fiancé then blocked her. After this she commented on another status of my fiancé's bestfriends and I commented below to be spiteful and she started running her mouth. I told her I wasn't worried about her and so on. She then said me and her needed to talk and all this but I didn't even write back I blocked her myself from my account. Every sence then I've constantly been on her Facebook to see if she's talking **** about me. I've also looked her name up on google, I know where she lives, all that. It's kinda crazy because I see everything she writes on her Facebook so I know whatever is going on in her life. My fiancé's sister has never really liked me just talked to me for my fiancé. She's never said she didn't like me but I know because of this. Every chance her sister has to talk to her ex she does. She'll go comment on her statuses saying I love and I miss you come see me which is at my fiancé's house because they still live with their mom. My fiancé only lives there until I can get all the money for our own place which is soon. Also another big thing my fiancé's ex is also engaged!!! It's crazy how's she trying so hard to talk to my fiancé and knowing neither of us can stand her. It might be because she's Is a drug head and constantly is doing drugs. It's kinda ridiculous. I'm a good girl, never done drugs or anything. I understand they was together four years but it makes me so mad when she try's to talk to her. I've been here for two years and aren't going anywhere. I don't know if that's obsessed or not. But .. I got a mess

 

The ex is also smaller then me so I know I could take her because I do know how to fight. That's not always the thing but the girl acts so bad like she's the strongest in the world. It drives me crazy.
