Need advice on how to work out on my relationship

Me and my girlfriend just started dating each other for about 2 months now. And as with every relationships, problems, big or small will always occur, and here is my story: My girlfriend think she is coldhearted. She really likes me, she knows her feelings for my are strong, but it seems like she kind of doesn't feel the love. The good feeling you get when you for example hug the person you like, when you get to hold her/his hand, just that tingling feeling when the person you like is near you. Why she feels this is way is a whole another story, but the reason is because her parents divorced when she was younger, thus making her get a bad relationship with her father. That again have caused here to have a bad relationship to men in general, and she thinks that is the reason why she is coldhearted. Because of this, she thinks it's unfair against me that she does not feel these feelings one usually do, and that we should stop dating if we can't work this out with her feelings. But she knows when I'm not there anymore, it will hurt like hell and she will miss me a lot (We broke up, and got together again because of that). I don't really know how her bad relationship with men is connected with this coldhearted issue of hers, but I know for sure that I need to do something that will make her feel these feelings. It's obvious that this also needs time to get things to work, but I really have no idea on what to do. She tries hard herself to feel these feelings, but it's hard for her to pretend to have these feelings, and it makes her irritated in the longer run. So in terms of that, I don't want her to force herself into these feelings, but do something that will make these feelings somehow come natural. I thank everyone who takes time to answer and give me advice on beforehand and I appreciate every answer I get
