Confidence / relationship

Me and this guy have been really close for years, and we used to date. We’ve spoken about getting back together, but not for a while.

Now I feel scared to talk about a potential relationship and tell him how I truly feel because I’m scared he won’t feel the same way.

I also am hesitant to initiate even a kiss because it’s been so long since we were intimate.

Any advice?

(I know it’s silly but with anxiety and low self esteem it’s difficult)
