So my bf and I have been together for about 16 months now and everything was fine, we've had our bad bumps in the road, broke up once for two weeks. We are great together and when everything's good it's good! When it's not...it's horrible. 

So we had a great Valentine's Day and everything went really well. I only get to see him about once a week most of the time so I do like to text and call him, but I always give him space.

Recently I was diagnosed with a depression and anxiety disorder because I've had frequent panic attacks this past week. I'm getting put on antidepressants. Yesterday I was supposed to go out with him and he rain checked to go out with his friends. I was obviously upset because I was really looking forward to spending time with him. We got into an argument and it came down to me being too clingy of a gf and "too much for him sometimes". I have no fucking clue where his shit came from. The conversation ended with him telling me he needs to think about our relationship. Wtf do I do? What does that even mean? 

P.s. I know it's not another girl because I had a good long talk with his best friend about this (who is on my side) and he would definitely know if there was another girl.
