...to feel left out

[Itajustagig]

Months ago I asked my bf if we could go and see a particular band. He said no as he was seeing a different band the day after. I was disapppointed but didn't want to go alone, so I left it. The day of the gig came round last week and he told me he was going as a free ticket came his way. I was a bit shocked as I had wanted to go and asked specifically. I had my DD but I could have arranged for her to go to my parents but he said no. No more tickets left. Suddenly, his mate is also going, the mate having got a guest list. This happens with every band I want to see. I haven't any friends to go with. I love live music and haven't been able to go to anything for 18 months. Apparently no guest list ticket could be found for me. I couldn't have either of their tickets.

AIBU for being dreadfully hurt that he decided to go when he told me he wasn't interested.

And a second one, AIBU for thinking this was planned weeks ago and he just didn't want to go with me.

I feel so down and a little unwanted.

Could he be a closet gay?

I really don't know anymore. Only that clearly I am not as high up in his priorities as I thought.
The ticket to him was a freebie, but why go when he said he didn't want to and then post on social media how much fun was he having.
There's been another argument over it today and now he's ignoring me.
Clearly I thought I was more of a girlfriend/partner than he does.
I just feel humiliated that I begged to go (and to other things), be introduced to friends/family and he is happy to keep me away.

We don't live together, to clarify.
