My girlfriend of 4 months broke up with me a week ago. This happened with zero warning or indication it was coming. On Friday she was crazy about me, very lovey-dovey, and on Saturday she said she was struggling. Wouldn't talk about it with me and just blocked me on Facebook and stopped responding to texts. I haven't heard from her since. Here's the thing, she's very afraid to love and be loved. She's had a rough life as far as love is concerned and once told me she'd run like hell when she started to feel love. I know she has feelings for me, I just know it. I've gotten two opposite pieces of advice on the subject. Fight for her or let her go and see if she comes back. Which method works best?
