my girlfriend keeps changing the subject to how i feel about her. i tell her that i love her very much and she just keeps changing the subject on me all the time when im half way through the conversation in telling her how i feel about her and when she does this its pissing me off.
girls please tell me why you girls do this for? and she 50 years old im 46 years old.
I've had a mariage before for 10 years and my ex wife did the same thing to me. now my new girlfriend who I've been living with for a year now is doing the same thing to me too. i just can't understand why it keeps happening to me and its really getting to me as i just want to settle down with a girl thats gonna love me 100%..

well i came home from work and she was packing stuff into boxes and she told me she's moving out and I've seen on her phone a whole heap of text messages that back dates 6 months between him and her talking about getting back together for another go.. so i take it she lied to me about him as she was talking to him the whole time behind my back.. so i take it she still had feelings for him then me.

Ask her straight up why she doesn't like you talking about her and your relationship. The only person who can give a good answer is her herself.

Could it be she hates guys now and wants to be alone after a abusive relationship with her ex and he's following her around to try and win her back. maybe to do it all again.

She's avoiding the question. That's what I do when I don't want to talk about something.

She has an ex boyfriend who she talks to all the time who she had a relationship with before me who abused her and used her but they have known each other from school. when they broke up she said to me that they were friends before they tried a 3 year relationship with and when they split up they made a promise to go back to just being friends. I just can't understand why you would be friends with an ex that abused you. is the part i just can't understand..

Ask her yourself for the most probable answer. Sounds like it makes her uncomfortable for some reason maybe
