Sometimes our wounds can be self inflicted. When you overextend yourself or exaggerate your position in someone's life, you're setting yourself up for a major let down when they don't respond with the same perspective.
It's already hard enough to deal with this in family and friendships, but then when it starts happening in dating relationships (or potential relationships) it can get toxic very quickly.
Free yourself before the bondage and simply stay in your lane. Don't allow your idle mind to create scenarios that simply aren't true.
