Should I walk away

I have been with my bf for 2 years. The past 6 months or so I have developed anxiety. I think the main cause has been broken promises and cancelled plans whereby I don't feel secure in the relationship. The past 2 weeks haven't been so good and I finally told him via text how I had been feeling (I haven't seen him in person for a couple of weeks). I told him about my extreme anxiety causing me insecurity and how I had been feeling low. He text me back but didn't acknowledge that how I had been feeling at all. Not to ask how I was, nothing. I had asked him if I was seeing him Friday for the weekend and he ignored my message and responded to everything but that. This is pushing my anxiety to an extreme level and I can't sleep. I feel after knowing how I am feeling is he triggering me on purpose? I'm starting to feel he doesn't care at all about me and should I just walk away from it. I did try to tell him about my anxiety 2 weeks ago in person. Twice. The minute I said "I am having anxiety", he spoke over me twice and I couldn't explain how I was feeling as he wasn't prepared to listen. I have been insecure in the relationship with him. 2 on and I haven't met his son, he is vague about a future (we don't live together but I have asked to which my response is I don't know). I always feel last place in his life but I am not sure if that's how he makes me feel or the anxiety. Little things like me asking him to call me a week ago, that I needed to speak to him. He neher bothered to call
