Single life.

Does anyone ever think that they will be single forever?  I have a soon o be 6 year old daughter that wants to become a big sister. I would love to make than happen for her. My last relationship I thought was going to be my final. We had a lot of fun we laughed a lot he loved my daughter but then things changed. And he started to push my daughter away. We have been broken up for 9 months now and I was fine in the beginning and now I'm missing him a lot and am still in love with him. It's super hard because I see him at church every Sunday and see him when he comes to my house for small group that we joined back when we where together. I want to just hug him and talk to him but I am not sure that he is into me anymore. But with the rate that I have been going with relationships I feel like I will never get married. (My ex and I were together for 2 1/2 years).
