Ok- so they have been friends for a while, but since we have been having more problems, they have become much much closer. He knows this woman from work, so they see each other there sometimes, but now they text each other over 100 times per day, they talk on the phone several times per day, and occasionally meet for lunch even when they aren't both working. I want to respect his freedom to have friends, but this relationship drives me insane. I feel so unimportant and insecure when he interrupts our time together to text her. I don't think he is trying to cheat on me physically, but it still hurts as if he is cheating emotionally. One of his many defenses is "she's married." I just don't understand how her husband can be handling this without a problem. Am I overreacting? Or is the level of his friendship inappropriate?
We are in our 30's and have been together for 5 years.
