Herpes Doctor

i have got a girl friend we have been together for two years now, during the first year we never have any problems and she never got any problem every thing was fine, on December on the first year she felt pregnant and 6 mounths on the line she got a miss-courage.
Since she got are miss-courage things does seems to be going fine between us, some time if iam in need to have sex she told me she doesn,t have feelings for me but she doesn,t know why coz she love me.
Some-time she says she feels pain during intercourse, or either some time if i come back from work i work to her she would just mood talking like she doesn,t wanna talk or she is sick or some thing.
Some time she doesn,t want me to touch her breast if i ask why she is like that she says i make her laugh if i touch her breast.
My question is why is she doing all this?. is she really telling the truth or there is some thing she is doing which iam not aware off, coz before she got a miss-courage there was nothing like this.
please help iam not sure whats really going on, only iam sure off is i love her so murch but every day its like iam loosing my trust on her coz since it started it doesn,t seem like it ever end.
IF is there anything i can to do or i need to do to solve this please help
