Ok, so few months ago, I've met a great girl at work, we had a great chemistry right from the start. We started going out for a coffee, walks etc. I'm not great with interpreting signals, but i guessed that she is pretty interested in me, she would text me everyday, call me sweet names, and casually touch my arms during a conversation, even our workmates gossiped that we are totally into each other. One time she asked me if i want to move out with her, so we planned the whole thing and became roommates. But few days before we moved in the flat, all of her previous behaviours dissapeared, now she doesn't even engage conversation, before she would even call me before sleep. I really enjoy her company, and I start to develop feeling for her, but don't know what to do next. It's worth adding that before she met me she ended a long relationship, and that she is 3 years older than me. What am i supossed to do not to lose her interest completely? Thanks ahead
