We just ended our relationship?

I have mixed emotions, I dunno how I'm going to deal with it. We had been dating for 10months and I can't have what I want. She broke up with me not because she wanted but because she felt she had to is what she told me. I want her to be happy but Im terribly afraid of not finding someone, cause I think guys are the chasers and I'm not really a chaser and girls aren't chasers so basically I have no one to get me. And guys are always after her and I hope she find someone. What should I do? Should I get her back? But I don't think I'm ready for a serious relationship yet I want her
