Gf still lives with ex fiance.

Hey I got something for you "Take everything and give nothing." Get all you can out of this chick because shes playing you. Your on the side like you guessed. Everything points to it. But have all the fun you can before its over. Or just start looking for a new girl. Better yet show up at her place and tell her family your her boyfriend and watch them run around like chickens with there heads cut off.

She still jumping his johnson, move on.

Ummm did she really break it off with her fiance? Well you didn't meet her parents and neither did you meet her? People lie all the time don't they maybe she's just cheating on him and your the other guy lolz. Don't pay attention to that just a little conspiracy theory I came up with. Now Imma be serious whatever her reasons what she is doing is just disrespectful to your relationship . This situation is not normal so you should just dump her. It might hurt you i guess (if you hesitated in that situation and looked for other people opinion you clearly like her) and maybe you might be tempted to believe her if she comes up with more and more excuse but sometimes the things that hurt us bad in the moment are far better for us in the long run. About revenge, I hardly believe it solve anything me in this situation I would just walk away (less energy wasted)

Dump her, but do it while you shagging her

Save yourself, dump her now.

Id always say that trust is earned and only a fool should trust somebody they doubt...never place yourself in a situation that makes you miserable and to be fair a lot of girls seem to have male friends but to live with one or actively consider moving in with one after they started dating you should tell you her respect for your relationship and if youve specified your dislike then her willingness to adapt her life for you.. any relationship isn't going to last if both people aren't willing to listen and act on each others fears, the only thing I can say is if you really must put yourself through this then treat her the way she treats you, go out with other girls, find one to house share with, preferably as hot as possible, make her very aware that you're giving her outlook on life a try and if she starts getting funny about it say well maybe you should try looking at yourself and the way you make me feel ..in all honesty I expect you'll end up with somebody far better through the experience anyway.. jealousy should never be knowingly brought into a relationship and its not pathetic at all, immaturity is a sad part of growing up but we all get there eventually and playing games with you is wrong by any means, if that was me id say get lost personally I can't be bothered wasting time with selfish women

I like sonking100's idea as well. I would tap that shit all the time and I would even try and score up a video or pictures of her naked or you guys doing it somehow. Take her for all she is worth. Make sure in a round about way you let her ex know that you been up in that shit too. I am hoping she is letting you bang her. If you aint gettin any from this girl end it now. Otherwise like said before here just get what you can and hell even start tapping another one on the side. After all what can she say? Good luck. There are a lot of ways to have fun with this. If you put your heart out there for this girl it will all go to hell. Keep it sexual and keep it fun and have a lot of back up plans.

This is definitely not normal. Dump her, dude.

They haven't really quite separated, and she is treating you as a second string. I don't think you should invest yourself emotionally in this a lot.

I agree, she is confused and maybe immature. She has emotional baggage, so maybe she is best left to it for now.

Yeah, something's definitely not right here. Go with your instinct and call it off with this girl.
