AITH for thinking my (26F) boyfriend’s (28M) inconsistently is a problem?

A little context to start with, we’ve been together for 7 months now so it’s still early days imo. I love him more than I’ve ever loved anyone and I do think he’s “the one”. We met 2 and a half years ago and started dating last year when we met up again after a long time. I’m from the UK and he is here on a skilled worker visa. This will become important.

Everything has been amazing between us, but in late January he had some bad news that his company was going bankrupt and would have to let him go by march. Because of his Visa, he can only get a job in his field and it has to be sponsored. It’s difficult to get work and it’s been a super stressful and worrying time for him. When he found out this news, he came to tell me and was essentially saying goodbye. This could be a red flag. But I told him even if he had to move away, I would still want us to be together and we would work it out.

Cut to: he’s been frantically applying to jobs and has had a few interviews now. He’s working insanely hard and has to study for the interviews as he works in the medical science field. I have been super supportive, I’ve given him space to study and work things out and have offered to go cook for him and clean his place if he needs it. He’s rejected this, which is okay as I understand wanting to be alone to work things out.

Last weekend, he tried calling me and I was asleep so didn’t answer the phone. He freaked out and thought I blocked him. It caused a big misunderstanding that I won’t type here as it’s too long. I found this was a double standard, as there’s been many times I’ve called him and not got a response but I haven’t freaked out.

He came to my place on Monday and I explained why this hurt me, and that his reaction was unfair considering he ignores me a lot of the time. He heard me, was understanding and vowed he will make time to communicate with me. Cut to today: I’m away for the weekend with a friend and I had an allergic reaction and got sick. I told him this 6 hours ago and tried calling a few times, only to be ignored. I’m not sure what he’s doing, or where he is but I’m now getting very frustrated and confused. His inconsistency is getting me down and when I’m sick, I want to hear from him because I was scared.

I’m not sure if I’m overreacting, but I tend to give people the benefit of the doubt and make excuses. Am I overreacting? I want to be with him and I want a life with him, but I’m worried it’s so early in our relationship to be having “issues” and I feel my walls are starting to go back up because of this. I don’t want to beg for my boyfriend to communicate with me…

TLDR: my boyfriend is inconsistent with communication and has vowed to be better with it, but is not answering the phone even when I’m sick. What should I do?
