Actually, I might as well tell you, I think I'm going to be joining you 
After everything, my boyfriend ducked out of coming with me on Sunday. We went out on Saturday night - he came to see me performing.
But it just brought everything back to me. How his ex girlfriends have all been sexy and gorgeous and exciting, and I'm just not. He said he had a lovely time and that he's never done anything like that before... but there's something that's just not right.
He was quite dismissive about not going on sunday and just said, "Hm, I don't think I'll go." and when I said that my family would be expecting him now and wonder why he hadn't gone, he just said, "I think it will be better if you go alone." He made some noises about it being a family thing and my niece would want to spend time with me, blah blah nonsense.
As it happens, what I predicted it would be like is exactly what it was like. My brother was the dutiful host, but ignored me because I'm his sister. My children were bored. Everyone else knew each other and chatted. Other than a bit of small talk, I spent nearly 3 hours sitting on my own 
You know all the good stuff, but I just don't think he's sufficiently interested. I feel insecure, anxious and unattractive. And this whole thing is just stagnating. He says he wants a future but there doesn't seem to be any effort on his part to achieve it.
If I flirt with him he ignores it, whether it's via email/text or in person. To begin with he just said it made him feel uncomfortable, but I'm starting to think it has more to do with the fact he just doesn't fancy me.
If I send him a longish (3 or 4 short paragraph) email, he'll reply with one sentence. And that will be it. I emailed him at about 6pm on Monday to say, "Have a good evening xxx" He replied at 1.00am to say, "Had a great evening, thanks ;-) " Nice. I have no idea what to make of it.
It's making me feel like shit.
I beginning to feel I have more meaningful contact with my exhusband than I do with him.
Not sure whether some of it is my insecurities, some of it is my prejudices, some of it is my... whatever... but it's starting to destroy the little self esteem/confidence I'd started to build up. I don't think he means it to. But I think he's running a parallel life. I can't think of any reason he'd want so little contact/communication with his girlfriend...
