<human>: I(15/m) think that she (16/F) is starting to have doubts, which is causing me to have doubts. We have been dating for about 3.5 months. its just that I feel she doesn't like me as much any more and that she is starting to not want to be in a relationship. One of our best friends told me that she said I was putting too much stress on her (apparently I try to hold her hand too often and stuff -she isn't touchy at all, I hold hold her hand maybe twice a day) and that she said that she didn't really miss me at school today (I was sick at home). The best friend also mentioned that she said she was hoping that her feelings would grow in the relationship and they did for a little bit but now have stopped. She mentioned that I push her too much to do things - which isn't true. The only situation where that happened a little was when I wanted her to try out for academic team (she is incredibly shy and I thought that she might benefit from something like that and plus it is fun) but when she got angry and refused, I let it go, because ultimately it is her choice. I always try to make her happy, and if it would make her more happy to be just friends I'd do it. I want to talk to her about it, but I'm not sure if i want to break up. Also, she is incredibly shy, so she won't take matters into her own hands and talk/break up with me. What should i say to her? And do you guys think that it might be time to break up?

Could you distill the essence of the text into 1-3 sentences?
<bot>: I think my girlfriend doesn't want to be together with me anymore, but she is to shy to come talk to me about it. What should I tell her, and is it time to break up?
