All my life I’ve had trouble with relationships. I would get attached quick, they’d leave and I’d be in a deep dark depression. I can’t stand to be separated from my fiancé and we are going through rough times right now . We’ve been together 4 years and both have had our moments when we talked to other people on social media. I had a mishap within our first year of dating telling other girls my relationship wasn’t that serious ( I would always downplay it to someone distant just in case I needed a backup if things went south so I’d never be lonely) . Her mishap was a few months ago after dealing with my jealousy and fear of her leaving she was so smothered she just started talking to people on discord. Joining nsfw servers and sending nudes to whomever paid her attention.  Fast forward to today I have major trust issues and she wants to go out and party / hang with her friend. We almost separated because she came in the house at 4am and I conjured up a bunch of allegations of what she was doing when in reality they were drunk and had to pull on the side of the road to sober up ( which was the story she told me ) . She wants space and wants to leave but I don’t think I can handle it . She’s decided to stay but from her mannerisms I can tell it was out of sympathy.  I don’t know how to proceed.
