I didn’t mean to click onto this, and I’m also not a girl. Plus.. I am also a week late to the question. I’ll still try to put an answer down though.
It’s incredibly hard to really see how things like relationships will turn out in the long run. People can, and do sometimes take advantage of you, but that doesn’t mean everyone always will. If anything less than you desired to become of this has happened to you, I’m sorry.
As for making mistakes, we all make decisions that we regret at some point. I know that this may not make it easier, but that’s about all I can say. I will also say that as humans, our perspective on life will change a lot, as time happens to us. What you have preciously valued today, may be of little concern tomorrow… (this sounds really cold, but it’s supposed to be comforting)
If you need anyone to talk to, if you’re still around. You can message me on here.
