Recently met up with an old flame. We had a brief relationship 2 years ago but it didn't work out for lots of reasons. He's been messaging me for ages asking to meet up so we did. We get on great. Have lots of laughs, never any problem. So we start seeing each other again then all of a sudden he goes quiet. Not answering messages, basically ignoring me. I called him out on it & he said he doesn't think it's going to work, that there's no 'spark'. I'm ok with that. After a few messages back & forth he changes his mind & says he wants to give things a go. I say no, stop messing me about. He then says 'don't give up on us'. Wtf is going on here? There is no 'us'! Every time we get close to anything like a relationship he backs off. I'm so confused! Am I being a mug here?
