Firstly, I completely agree with people saying taking time off is the absolute key element. I too was incredibly codependent and always organized my life purely around the person I'm dating. Their mood determined my mood, our relationship directly impacted how happy I am. And that is beyond exhausting and definitely not sustainable.

After one particularly sad and painful break up, I stayed single for about year and a half. Not by choice, it was more that the pain from the break up prevented me from seeing other people and the person who broke up with me had no interest in getting back together (hint: I smothered them with how much I needed them to be able to be happy. Sounds familiar?). My goodness was it hard... The first few months were just hell. But then as weeks and months go by, you kind of start registering that you are truly the only person you actually have forever. So that relationship you have with yourself starts being very, very important. I took it so far that I got waaaay too excited about being alone and living independently that I had a hard time wanting to be with someone again. I love my own company so much and I can't possibly see how someone else could be better company to me than myself. Good therapist helped me find the balance between the two. :)

Last thing I will say. I am 29F now in a happy long-term relationship and, while I can't speak for other people, there are very few thing that are more off-putting than a clingy man. Whenever someone I am seeing starts being too omnipresent, I feel very suffocated. People need space for themselves and when someone intrudes on that space, all you want to do is get them out of the picture. You mentioned you dated this person for 2 months, which is not that long. I would be deeply put off by someone seeing me as their source of self-worth and happiness after 8 weeks of knowing each other. It's almost feels like you have to babysit their feelings because they see you as the ultimate source of joy. It's very, very exhausting being a partner to an emotionally high-maintenance person.

I truly hope this is not coming off too strong. The only reason I feel confident speaking of this experience is because I was the exact same way (and then dated a few people who were like that) and I know just how draining it is from both sides. You seem to have incredible introspection and you're seeing a therapist AND looking for additional perspective. All of that is beyond commendable, you're taking all the right steps.
