Girlfriend of 5 years with kid together coming back after NC for sex

[emty187]

Hi everyone.

 

Long story short: Been living together for 4,5 years been some on and off the last year. She even cheated at me once when we had a hard time, with a random guy in the her sisters birthdayparty... in May i found out she was using snapchat behind me back and texted+sexted a guy she meet. I flipped out and she said she didnt want to be with me anymore. I Took it cool and said i was out for good, and i blocked her on facebook ++its impossible to go full NC when we have a son on 2 years 50/50 together..For the next 4 months I only talk to her about things related to my son. But for like 2 weeks ago i talked to her and i said i was no longer mad at her, I deblocked her on facebook and we started to talk about how she was doing in life and how shes been. The bottom line is that she asked to come over for talk, since she didnt knew anyone so good as I did. I said ye NP.. We talked, had fun and hooking up. The last two weeks shes been at my place 3 times for sex. She is saying she dont have feelings for me, but when i comment other girls asses in music videos she gets grumpy, just like when we were together.

She was also soar when i said me and my friend was buying some cool ass haloween costymes for a haloween party... She also checked my facebook messages at my computer.. Just or seeing what girls i had been with...

When we wake up in the morning after, shes always saying she only want intimity and sex with no attachment..... The bottom line is that i love her..

I dont show her, I keep make her think that i have other girls and a great life but i want her back..... Should i just have fun with her as long as it lasts, or should i go back to NC ?
