Questions: Dating

(F20/M26) We went on vacation over the summer and we ran into each other again recently. She’s had a boyfriend of 3 years this whole time, yet she asked for my number and asked me on a date that we actually went on. She texts me flirty things and says she wants to cook for me, sit in her hot tub with me, etc. This has been going on for a month.

Here’s the catch. She doesn’t want to escalate until she leaves her boyfriend, but she isn’t doing anything to leave him.

I’m tired of being the man in the middle. It’s a really shitty situation to be in and I’m getting really bored. How should I end it?

What are your height preferences when it comes to dating?

I am 28 years old and never had a real girlfriend. I haven't even so much touched a women in over 7 years. I almost had to sell my soul to lose my virginity to a teen several years younger than me when I was 20.

I am mostly introverted and short in height (5'6). I spend a lot of my time engineering web apps.

I have been told women today have set their standards so high that they are almost impossible to meet by the average (and below average) man. Sadly, most of my peers I have known growing up are married with kids. I am left behind.
