Anybody left a relationship because intimacy/closeness got to be too much?

For those of you who have read my posts before, I have been struggling over the end of a relationship. So much so that I have severe depression and suicidal thoughts.

I go to therapy twice a week and see a psychiatrist once a month. I also take antidepressants every day and occasionally anti anxiety medication.

Despite everyone saying just get over it and just let go; it isn't that easy given my past. What particular eats at me is that everything seemed close to perfect for the 9 months we were together... lots of physical affection, lots of fun activities, good physical intimacy, lots of declarations of love. He pushed me into all kinds of interactions with his family members and insisted on being part of mine. And then, within a matter of weeks, it was over. He said it was too much stress...

I keep thinking I did something wrong or he wouldn't of left. He also completely shut me out. I've read some articles that have said some people will leave because a relationship becomes too emotionally risky/close/vulnerable. If you have done this ever, please leave me a sentence (or more).

I'm not looking for "ways" to get over this relationship (although if you want to say he's a dysfunctional jerk, that's ok, lol). My therapist and I are doing the best we can to get me to move forward. I just really want to know if anyone has actually terminated a relationship because it got too scary.

I have wanted to. I was feeling smothered and he wouldn't back off even though I was telling him I was uncomfortable.

I didn't though. I was more scared of being alone than my lack of personal space.

Getting close is scary especially when it's never ended well before.

I'm guessing he's got some sort of dismissive avoidant attachment style happening?

I'm sorry you're hurting so much.

You are very kind. Thank you. I had not heard of dismissive attachment style before, so I looked it up. He does seem to have much of that.

Yes, I have left a few relationships (romantic) because I felt overwhelmed and scared by emotions. I have a tendency to feel rather suspicious of love, due to my upbringing. Even in my 14 year marriage, 17 years commited, I had a very hard time letting myself feel emotions.
