Just thought I would let you know that I can relate. I also have commitment issues and it confuses the hell out of me. I met a guy who was in every way perfect for me, he had a great job, he was in love with me, he was very handsome, he bought me gifts just because he felt like it, he was understanding of my mental issues like depression or anxiety - he was literally perfect for me.
One day, I freaked out. I felt a crushing sense of anxiety and felt a strong urge to break up with him because I felt like I couldn't handle the relationship, I also felt like he deserved better and that I didn't have the energy to be in a relationship.
So about a week before I broke up with him, I cheated on him with a man who I wasn't even attracted to.
I had no idea what I was doing!

This happened last year. I realize I do have commitment issues because of my childhood.
I still have hope that I can have a healthy relationship.
And I still think you can too.

Two things have to happen for a healthy relationship to last.
YOU need to be in a good spot in your life. If you aren't content with where you are in your life, it doesn't matter if prince charming knocks on your door, it won't work.
You also need to find the right person who meets your emotional needs.

So those 2 things need to happen to make a commitment work.
And they can happen. Perfect timing is a real thing.
