Hi,
Would appreciate some advice please.
Long story short I met a guy OLD, we went for a drink got on well, he text afterwards and we arranged to go out the next week. On the morning of the date he text and cancelled due to illness in his family which meant he had to go away. Since then we have had texting conversations and he's very flirty but sometimes if I text him he doesn't reply. It drives him crackers however if he texts me and I don't reply. We often make preliminary plans to go out but on the day of the arrangement he either goes quiet or cancels for one reason or another. I called him out on it once before and he said he panics etc and he was really sorry because he really liked me. However, this week we were supposed to have plans this week and he let me down again stating he had rang me but my phone wasn't working. Turns out he had rang my old number.
Following this, I text him saying that it was getting complicated and not working out and that I was ending the contact. I blocked his number, mostly because I really fancy him despite his behaviour and I'm not sure I have enough control if he were to text not to reply. But I feel by blocking him, I am being a bit childish and showing him that he is bothering me. I think part of me also wants to he if he does message me which obviously I can't see if I block him!
So now I'm in a complete quandary about what to do and how to proceed with this whole thing. He has me demented 
Wondered what other people thought of his behaviour etc and whether I am doing the right thing by blocking him?
