It's now 2 months since my ex left me. We'd been together a year, he was controlling and my mental health was deteriorating for the last 3 months because I'd come off my antidepressants. He didn't even know I was on them as wouldn't have approved. I'm now back on them, having therapy and in a much better place but I can't shake this feeling of regret - that if I'd been different we would have lasted.
Any tips on how to move on?
