Advice needed!

I'm feeling really down.

Since the pandemic started I wasn't able to see my boyfriend, so we are kind of experiencing a long distance relationship, he told me that as soon as everything will be over he will move abroad because he can't stand his family anymore. I won't be able to go with him because I need to work to save money. The issue would be I don't think I'm able to have a long distance relationship because I have attachment issues (mind that I'm doing therapy to overcome many of my mental and behaviour issues) I basically can't feel a person unless I'm near to that person. I'm not ready to leave him because I love him and feel like we can have a future together but I don't see how could I handle the situation, thinking that now that we don't see each other for more than a month I already feel less inclined to video call him and spend "virtual time" with him. I can only imagine over months and months what kind of tricks my mind will play with me. How can I feel him close? How can I don't end up hating him because he goes? I love him, but I know me, and I know how complicated everything can be.
