So she's been my girlfriend for 2 months now and we had a really great relationship (some fights, but we got over them), up until I've travelled for university. Before travelling, she always used to say things like "if we don't talk for a day or two, don't worry it doesn't mean we lose feelings for each other, it's okay if we know where we stand with each other" "we got to trust each other" bla bla bla. After I travelled ( for 2 weeks now ), we stayed in strong communication for the first week. This week, she's not asking about me like she used to, she's not opening conversations like she used to, and whenever I bring something related to our relationship up she tries to change the conversation and not talk about it. For example, on our two months anniversary I asked her on the phone "How do you feel that today it's our two months anniversary?" SHE LITERALLY CHANGED THE SUBJECT! I got no answer. I'm very confused what happened with her; she used to be the one that talks about our relationship, she kind of changed her behavior with me, she doesn't send me good morning or good night texts anymore, and I'm starting to get worried as ****. I've tried taking a day or two off from her, I didn't text her, she texted me saying "I just registered for my uni. Yay". She didn't even ask how my day was going, what's up with me, etc..
Anyways, you get the idea. To be honest she means a lot to me and I don't want to lose her, so please refrain from ideas including "leave her, there are plenty of fish in the sea" bla bla.
What I need is a solution to my situation. Anyone?
