Yep, I pretty much had the same attitude, into my 40s never had a bad breakup with a partner, never regretted a relationship, friends with most my exes. But with this one, blew through a bunch of red flags but they really wanted to stay with me, so figured what's the worst that can happen? I almost didn't survive the aftermath of the breakup. To rest of you with a similar experience, I'm really sorry and hope you recover.
