<human>: Condense the text into a few key points

Two years ago I divorced a man who treated me terribly. I was with him from the age of 18 and only dated a couple of guys before I met him. I've always been interested in lesbian porn, but never really thought much about it other than it was a fantasy type thing. 

After my divorce, I dated a couple of men, but things didn't work out for various benign reasons. Anyway, to cut to the chase... A couple of weeks ago I was on Tinder after a couple of glasses of wine. For some reason I decided to look at the women and ended up matching with a few. It seemed kind of fun (which in hindsight makes me feel like a bit of an asshole.... I wasn't there just to gawk, but I also don't really know what my intentions were) and then I matched with Hannah. 

Hannah. This girl is amazing. Like, AMAZING. She's so sweet and funny and we've been texting non-stop ever since. I'm also ridiculously attracted to her. I've never felt this way about another woman and I can't remember the last time I was so turned on at the thought of getting intimate with someone. She's just... Amazing. Every time I get a text from her my stomach flips and I end up smiling like an idiot. We've discussed meeting up and I want to, so badly. 

This brings me to my dilemma. I'm now beginning to assume that I'm bisexual (duh). But that also means I'm in the closet. Also, I've never actually been with a woman - she would be my first. Also, I really do feel like a bit of a jerk because Hannah knows none of this about me and I'm scared to tell her in case it turns her off. 

Should I tell her? She doesn't even know that I'm bi. She identifies as gay but has never asked me the same. Should this be a conversation that I have before we meets so she can make an informed decison? I so desperately don't want to disappoint her, but also I'm just so excited to have met her. 

Please help. Where do I go from here?
<bot>: Met gay girl on Tinder. Didn't know I was bi (thought I was straight with lesbian fantasies (does that even make sense?!?)). Do I tell her?
