<human>: About two years ago, I fell in love with Girl A, but wasn't sure if she loved me back so I didn't do anything. A couple of months later I start dating another girl for about a year and a half. Around the last four months of dating with the girlfriend, I increasingly started hanging out more and more with Girl A and needless to say, I was still in love. After me and the then girlfriend broke up (beginning of october) , a week later, started becoming casual. FWB, and has progressed to a point where girl A is starting to fall in love with me.

I've never really been the one to have a single life as I've never tried it before. 

About two days ago (four months later from breakup) , Girl A calls and tells me her feelings for me. Everything should be perfect as it is, but now those "single life"  thoughts are crawling back and making me hesitant of going into another relationship. I am still in love with Girl A however but don't want to lose her at any cost, if I do make a bad decision. 

Is four months after a breakup an appropriate time to date and am I being delusional with all the single life schtick ? She has been the one I've been eyeing down for the last two years, and this is quite a dream come true. 

Thanks for listening.
