My best guy friend of two years confessed to liking me on valentines day, and we've been talking/dating ever since then. For some context, I did have a crush on him when I first met him but nothing ever came of it past that. I just exited a relationship of a year in early January and it took a toll on me, but I'm over the guy, not sure I'm over the abuse and lack of support I faced.

I feel like I'm already falling into my insecure and over critical ways with him, or my bpd relationship ways I'd call them. Part of me feels like I'm just projecting from my ex because I was so unhappy towards the end and resentful of how I was treated. I can't tell if I'm just damaged and scared of it, if I'm just adjusting to seeing him as more than a friend, or I don't see him in that light. I do truly think I'm over my ex. 

Any advice or input past just seeing how it goes over time? Thank you!
