Search Results: giving him another chance

Met a guy at work who would make me laugh and I found very attractive. We'd flirt all the time but he had an on and off relationship with a girl he'd been with for 4 years. They had a baby and ended the relationship, had a one night stand and had another child.
Before I went away for holiday, he had started visiting where I work after having leave for an op. he was flirting with me heavily and took my number.
When I went away I had a bad experience with a guy which wasn't consented. When I got back I wasn't myself. Sex wasn't very important to me.
We met several times, he lives quite a while away so I would stay over but nothing happened till the 3rd night and it was all on my terms. To begin with it was just sex and I knew that. But it grew and we became more intimate in other ways. He told me he loved me very early which worried me but after giving him a chance to take it back I didn't think about it much.
I realised majority of the relationship was staying indoors eating junk food watching films and listening to him talk about his ex. It was hard because they were still in contact as they'd had children. However I felt like I was a shrink rather than his gf.
8 months later I decided to go on a break so he could get his thoughts together - his ex is on cocaine and is sleeping around with the kids in her place. He had every reason to be worried.
Recently we met up to talk as the break wasn't helping due to is still working together. It was clear he's not over his ex, which was an issue raised early in the relationship. He didn't know much about me. I asked him questions which he couldn't answer. Yet he was saying everything is been feeling for the last few months. It was confusing.
My worry is that I'm a rebound and that even though he sometimes seems like he cares, I mean nothing to him.
I suggested friends with benefits after sleeping with him (after which we had a deep conversation) as I don't want to lose him as a friend but I don't want to be fucked ov

So I went out on a date with this guy. He's really nice and sweet and I like him, he's kinda geekish, but I like that... And he's definitely an introvert, which I have no problem with. The thing is that I like that we spent some time together and I want to write to him, but there's a chance that he didn't liked me (I'm saying that because I'm insecure and of course because it's impossible to be liked by everyone on earth). There were a couple of awkward pauses during our conversations, but they didn't last long and didn't really bothered me... So now I'm thinking that maybe I should write because he's probably thinking the same as me, or... He didn't liked me and if I'll write to him he'll think low of me and I don't want that... We went out two days ago and I wanted to write to him ever since. But there's another thing that's holding me back... When we met, he hugged me, but when he walked me home and it was time for us to separate, we both just said goodnight and maybe he was giving me a sign of rejection... :/
