Realizing I have an anxious attachment style and my boyfriend is avoidant

Hi all,

thanks to a member's answer I have done some reading and realized how much I fit into the anxious attachment style in all my relationships. And also how my partner fits into the avoidance type.
I have have been through some counseling before as I have suffered anxiety and panic attics that finally led to a depression. This was at the end of a previous relationship that was very much toxic but I held on to and only when I left did I start to recover. This was 10 years ago and I haven't had any relapse since.

However, I am now worried I am feeling very anxious all the time and finding it hard to focus on anything else. I can't enjoy being with my partner because I feel resentment that we aren't dealing with the issue I can't stop thinking about. I have explained this to him and he listens but I never feel satisfied with his answer, like he isn't committed enough to me and our future.
Our problem is that we can't carry on just being a couple living in our separate houses as he is going to leave the country soon for a long period of time and then most likely accept a job in another part of the world.

I am his first long time partner (3years) and I know exactly has made an effort to show me I am important but I need more, I want to be with him in an adult relationship that leads to marriage and children. And I'm worried I'm pushing him to much and I can only see two outcomes: we break up or somehow he makes me feel secure....advice please!!
​thanks so much
