Emotional needs

Hi. I’m currently having a crush on someone and I feel like doing the first move. However, I am still thinking what if I’m not healed enough to love someone else? Fyi, it’s been 6-7 months since my breakup and sometimes I still caught myself thinking about my past. I am not sure how do I cope with myself right now. It’s optional actually, I could have just brushed it off about this crush thingy but I kinda want some connection.

I did reflect on myself from whatever has happened before. I am still focusing and improving myself to be a better person. Now the question is, should I just let this crush feeling lingers in my mind and make a move or should I just prevent myself from knowing someone new because I’m afraid I might hurt them.
