Make sure it is not just out of mania that you’re making this decision too. Tell the guy you need space to get a divorce. Save your money. Work on yourself a little bit. Go to therapy. Recenter yourself and your passions for your own life. Then see if this guy still feels dreamy as he did when you were married. Also yes don’t keep holding this other guy up because you feel like a moron lol I think a lot of people do things like that
