I've been talking/dating/hooking up with this girl for over a month now. Everything has been great. We decided to become official last week, and now everything has changed. All of a sudden less than week after we became girlfriend and boyfriend she became very distant and we decided to take a step back removing the titles.

There was never any fight or any sign this was coming. She simply said we needed to slow down and go back a bit. She's concerned with having to adapt her life to having a boyfriend and wants to operate on her own schedule. We are still talking, still kiss but she is still distant and reluctant to have any further contact or cuddling that was very common before this randomly happened.

Does anyone have any advice on what to do and/or what might have caused this?

Maybe she has realized she does not want to date you. It's only been a month, break up and be done with it.

Coming from a females.perspective to be honest she was feeling you as a "friend"but once y'all decided to put a title on it she realize she doesn't see you in that way so she's trying to back away without really hurting your feelings... theres not much you can do if you really like her back away from her and ignore a little bit if she shows signs of pursueing you more than that's a thumbs up if she shows she doesn't care your ignoring her.. just leave her alone and move on.
