I'm tired of my girlfriend talking about her deceased ex-boyfriend.
Is it because you feel she spends too much time thinking about her ex-boyfriend?
Yes, I think she was more in love with him than she is with me.
I'm sure you're frustrated that your girlfriend thinks about her ex-boyfriend so much. Talk with her and tell her how you feel. She may not understand that you're upset about this issue.
I will.
I'm glad that you've taken this to heart, and I hope that things work out. Sometimes people don't realize that they're hurting ones that they love, and she probably didn't mean anything bad by it.
