.....I just called my therapist...I don't know where these strong emotions are coming from or what they are about. I needed to react so I did...and now I feel calm. Calmer. but, until when? This woman is flattering him. Big time. He has a constant need for people to reassure him because his self esteem is so low.
You are spending a lot of your time focusing on him where it will be better spent on yourself.
Who cares who he is seeing. Who cares what someone else is saying to him. He is not your boyfriend anymore. At this point you guys are only exes who are friendly. Let him go so you can work on yourself. Can you tell him that you have his password so he can change it so you're no longer tempted to snoop on him? Not only are you torturing yourself but you're also majorly violating his privacy and betraying his trust.
