OP, I'd like to ask how has this helped you in any way? I get that you might feel insecure and vulnerable in a relationship and want to change it, but how building a wall around yourself can help in any way?
Being in defensive from the start is not the way to start a healthy relationship.
There are lot of bitcointalkers like these. Especially the young ones, earning bitcoin is their motivation and girls are not really their thing, they are not nerds but they are weird. Friends that I know using bitcoin, have girlfriends of their own. Saying these, this type of person is more likely the true lovers when they find the right girl, and I am envious with these kind of people because they prioritize their own selves than love, it is quite the opposite to me, and I think it is taking the toll on me.
Being an egoist is really nothing to envy. If your girl's needs are more important to you, you are good the way you are, you just need her to appreciate it. Don't try to change yourself to adapt to society!
