Hi and welcome. No one except your boyfriend can tell you what he means but depression in any form does often cause us to push the people we care about away. It is tough for our friends and family to deal with and sometimes things just don’t work out. Having said that, it can work. My husband and I are stronger because we were able to work things through. You need to have a proper conversation with your boyfriend and ask him what’s going on, if he needs space perhaps he needs to give you an idea of the boundaries of that?
