I deleted my Facebook account in 2012. Haven't missed it. Let's hope this poor soul can finally be brave enough to find the close account button. Might not even need to write a script to do that.
Thanks for being brave enough to share this, and I feel sad you've had to be on the receiving end of this disgraceful behavior. However, I think the levels of appropriateness really doesn't go far enough. It still treats women, sex and relationships far too casually. So here is my suggestion instead - MEN LISTEN AND TAKE NOTICE：
1. If you like a girl, ask her on a date, face to face, or send some flowers. If she declines two or at most three times, give up. She's not into you. Leave it at that.
2. If she says yes to the date, get to know her, find out what makes her tick and how you can care for her. Find out if shes willing to let you kiss her, maybe after a few dates.
3. If things go well, you can propose. Ask her parents or close family members first for permission as far as you can. Think about how you can love, support, help your wife to grow as a person. Think about how you can make her happy and what responsibilities you will need to take on as a husband.
4. Get married. After that, start to talk about what your sex life will look like, what she feels comfortable with, and when even if you are married, make sure you understand that sometimes she won't want to have sex. Then, enjoy yourselves！
Anything less than that is not good enough.
Leave off on the alcohol is probably a good idea too, you can easily get into trouble doing things you wouldn't dare to normally.
I think you need to deal with this before you get to the edge point. You need a way to understand your own emotions and why you are feeling like that, and start to resolve underlying things like stress, strained relationships, existential angst like what is the point of work etc. I find praying to Jesus the Messiah helps me a lot.
