Reciprocating inadequately

Well there's this principle I learnt that you sorta need to reciprocate what your "partner" feels.

I am socially anxious.

A girl sorta ended up confessing that she liked me and she planned a date on the weekend , but I didn't go.(I had negative experiences in the past and I was scared. It was still my fault that I didn't act).Then she did stuff that ended up fucking my mental state up.After a while we started to get back.I guess you are supposed to put in a little extra effort in the beginning so that both the parties kinda get comfortable with each other.

She tried to help me deal with my social anxiety cuz I wasn't really talking.Something that I did before when I was mentally "not same" messed stuff up even more.

We finally tried to sort stuff out.But I didnt really state the problem.I told her through some other medium which we use to communicate indirectly,so she wasn't able to put out what she feels.

I sometimes feel like since she put in too much effort in the beginning we are getting nowhere and its just the two of us playing games at this point.

I genuinely feel like this person is worth being in a relationship with but we are severely f___g things up.What should I do?
