More than a friend

First of all no judging! So I got out of a relationship almost a month ago because my ex couldn't handle me with my anixety disorder because the fact that I was sexually/aggravated assaulted and I had bad anixety and depression to the point I wanted to take my own life I have this friend who pretty much was there for me for all of that and never got upset at me once for my bad mental episodes anyways a few weeks ago I went on a date with him two weeks ago and I have another date with him this coming Saturday and I'm actually starting like him a lot more than just a friend but I'm kinda scared that if I do get with him I'm scared all the happiness I feel with him now fade cuz of my last reletionship but I'm also thinking he's a lot different and more mature than my ex and I still kinda wanna wait awhile to get with him still what should I do?
