does my ex still like?

going back about 7 months ago i was in a relationship with a 32 year old man(i'm 29) and everything was going great between us and i was very happy to be with him and he seemed happy as well. he used 2 tell me that he loved me, that he wanted kids with me(even though we were only together for about a month) and how much he wanted to be there for me where loosing my mum was concerned(she passed away 2 months ago at this point). after about 3 weeks he seemed to change and i got the impression he wasn't interested any more. i asked him what was wrong and he finished it with me saying that he didn't have time for me because of his job( he runs a pub) and how much he doesn't trust women after his ex wife cheated on him. i saw this as being a big of a cheap cop out because if these were genuine reasons then why would he ask me out in the begining. on a more positive note he said he wanted to be friends and about 3 weeks after we split up we went for a drink as friends and he even said he wanted to go for another drink again sometime. i agreed to this and text him another 2 weeks or so after this asking if he wanted to go for a drink again like he suggested. it seemed like he was ignoring my text but just in case i got the wrong impression i text him again another week down the line. yet again i got no response.this behaviour continued for another few weeks after. feeling very confussed to why he'd be like this as it was him who suggested about meeting up for a drink in the begining, i text him asking him what was wrong and could we talk about stuff because i'm feeling very confussed. to my surprise he actually text back this time saying that we could talk. when we met up to have a talk about why he was ignoring me he hardly had anything to say to me which made me more confussed and angery with him as like i said, it was HIM who wanted to stay mates. to cut a long story straight, things come to a head and he made me so angery that i ended up throwing a drink in his face. went back in the pub where he works about 2 month after this when i thought things would have died down and he didn't seem like he wanted to speak to me. i was ok with this as at least i knew where i stood. another 2 month after this i went back in there again and yet again he didn't seem to speak. this time another guy was flirting with me in the pub and i got the impression that he felt a little awkward. anyway, i went in the pub again back the other day and to my surprise he seemed really chatty towards me almost as if nothing had happened between us in the past. he seemed to talk to me like the way he use to talk just before we got together. i feel a little confussed about his reactions because if you look at the situation over all. first he asked me out, we go out for a month with him saying all these nice things to me about having kids ect, then he goes cold on me and eventually finishing it with me, then he wants to be mates, then he ignores me as a mate and doesn't talk for about 6 months after this which 1 time looking really awkward when someone his flirting with me, and now hes really chatty towards me. does this mean hes just making an effort to be friends or does it mean that he still wants me. if so do i say something to him or not as i still like him as well and never wanted to split up from him in the begining. i'm also wondering if him looking awkward the time this guy flirted ment that he was jealous
