My friends are dating
Obviously, abuse issues are a huge red flag and need to be dealt with directly.Or, sometimes the boyfriend or girlfriend may appear to be overly controlling, demanding, or demeaning. What they are doing is really uncool and unacceptable. Your ex and "your friend" are the ones who should feel stupid, NOT YOU! Their relationship is working because of the "scandalous and forbidden" element. When that wears off, and everyone in the community moves on to the next piece of gossip, and your ex and your friend really get to know each other, the appeal will fade. He or she could be doing this to you to act out his or her passive aggressive anger.
This means you’re unbound by your current limitations and can meet people you would never have come across otherwise.
If your friend is in a relationship that diminishes self-esteem, rather than enhancing it, pray earnestly and look for ways to build up and encourage your friend.
