I Feel a strong attraction and wants to be a lot closer but I don't know what to do
There's this girl I've been friends with for some time now, for about 3 years. We dated for 5 months the first year we knew each other and then have remained friends ever since. I've started to feel attracted to her yet again (it's actually really strong attraction towards her) but I have no idea what to do. My brain literally just shuts down when I'm with her and I just become this cocky guy that doesn't really know what to say. I'm pretty sure me and her are good friends but I just really want it to go a step further than that. Please help, I have no idea what to do to reach my goal.
