I’m really struggling to get over someone I only dated for 4 months. I know I’m being ridiculous, I am more upset/hung up over him than I was when my 6 year relationship ended 
I know it’s cliche but we really had a connection
we both felt the same way and it felt like everything was falling into place. Then he started having random fits of jealousy, he acknowledged he was unreasonable and explained he had some MH issues and trauma/abandonment issues.
I had to have some boundaries around how he was being, which long story short ultimately led to the end as I refused to pander to any jealousy/oddness.
He was the first person I dated after my LTR ended, which was quite emotionally abusive and controlling so I’m not sure if that’s why I’m so hung up on things not working out. But I just can’t get my head around it - it really did feel like the sort of connection you don’t find many times in your life, and I’m usually quite sceptical over things like that.
we’ve been no contact for 6 weeks now, I felt better at first but the past week or so I’ve been really ruminating and having odd dreams
I haven’t felt this low in a long time, everything feels a bit flat and pointless and sad. I think it’s triggered a bit of a depressive episode for me; which I know is really silly and OTT.
Any words of advice please?
