I just got out of an engagement of two years. I finally had the strength to leave after being unhappy and expressing it various to my partner which would cause nothing to change. I noticed he was going downhill and going back to his old habits (smoking weed and just drinking more). But once we broke up he already has a new girlfriend, seems to now have his stuff together, and just seems happier overall. I feel like I’m here stuck even though I broke up with him. I find myself thinking did I make a mistake but I know it’s too late now. Do you have any advice?
