I like someone but they won't ever like me back and that's ok. It just hurts and I need help getting some ideas or reassurance so I don't do the typical BPD thing and go do the impulsive thing I want to do (dye my hair again, date some random person I don't like, etc). I've been single for 3 years now and I know I need to stay single to work on myself but I also need to get friends so I have a support system but it's hard to not flirt with everyone and just date anyone who has an interest in me. Any tips?
