No affection

So me & my husband have been married 10 years. We’ve been together since he was 19 & I was 17. About 6 years ago when our youngest was born I noticed that our relationship started to change. He stopped being affectionate. Like he could go days without touching me or kissing me. I know because i purposely stopped initiating hugs & kisses & he didn’t even notice. So the last few weeks we had been doing better. He has been communicating more until a few days ago it’s going back to how it was. I feel like he’s annoyed with me. It’s been years since I’ve felt pretty. I thought I wasn’t for the longest time because my husband wasn’t giving me attention. I recently met someone, we flirt a lot & make eye contact. He tried kissing me but I didn’t let him. I guess what I’m trying to say what do you do when you don’t feel seen? Or your relationship just feels awkward? I’ve asked to go on dates & spicy things up but nothing ever happens. Our sex is AMAZING but that’s about it. I’m not the easiest person to be with. I have really bad anxiety so I feel like I’m a burden on him. Like sometimes when I go in for a kiss or hug he already has his arms on mine ready to pull away. I don’t want to end things but my anxiety is also like you only get once chance at life is this how we are going to live it?

ETA: I have talked to him multiple times about this. & nothing ever really changes. I’ve suggested therapy & he doesn’t want to try it. He has said he can’t give me what I want right now because he’s so focused on work.
