I’m an anxious attachment style and I hate it

I’m(F20) an anxious attachment person for sure, just like my dad. The smallest amount of difference in texting or voice or emotion triggers me but I know my bf(M19) loves me. We sleep call every night, play and talk all the time, text each other randomly, etc. While I’m an anxious attachment, my bf is an avoidant attachment and he also got out of an emotionally abusive and terrible relationship. I want to support him and make him feel safe which I feel like I do really good !!

I just feel like he was a little different than last month, like he might be pulling back. Maybe it’s just me, but maybe it’s not. I want to tell him I’m an anxious attachment but don’t know how to tell him. I also always say you can talk to me about anything whenever but you never have to if you don’t want to. I feel like hes pulling back, what avoidants do, emotionally pull back. Like when I say I love him, which we used to do all the time when we first got together, he doesn’t say it back. It’s making me feel anxious and scared he doesn’t love me or I’m not for him. We were so flirtatious and sht even before we got together. I don’t want to drift, I don’t want to overwhelm him.

What can I do to make him possibly feel safer as an LDR? I will always continue to tell him how much I love him, but the anxious attachment trigger goes off when he pulls back. How do I not become triggered at this?
