I will have been with my boyfriend 1 year next month. We've been through alot together and I love him with all my heart. Not long after we got together, I suspected something was up so while he was in the shower I went through his old phone that he uses alot but I didn't know what for. There were no messages sent back but a few from his ex. They were together on and off 4 years. She'd say stuff like she misses him. I confronted him and he said she does still text him now and then but he never replies. She cheated on him so many times and hurt him so much. He thinks I'll do the same because in his eyes "all girls are the same" because one girl hurt him.
Anyway, that was it. Then 4/5 months into our relationship he came up my house early hours in the morning really drunk just after having a night out clubbing. He carries his iPhone and his old phone around with him everywhere. Not anymore but he used to. I went through it again and noticed he had sent a text to her that same night saying something like "Everytime I think of you I wish I didn't exist". I went mad the next morning.
Last month, she messaged him on Facebook saying "Why were you outside my house last night"? I asked him, again angry and he said he wasn't and said she's using excuses to make him reply. I let that one go. Not long after this I went onto his facebook through his phone without him knowing and in his deleted one was a message from her "I just want to say I'm sorry for everything I've ever done to hurt you". He hid this from me. He talked his way out of that. Now yesterday she tried it again! I'm FURIOUS. If I knew this would happen trouble with his ex I would never of got with him. He says I need to ignore her because he doesn't reply. Anyway I don't know her personally but have found a few things out about her. And I know she has a boyfriend.
So tonight in my anger I added her boyfriend who she's been with him 5 months and he messaged me saying "Do I know you?" I said no but I've seen him around. He asked where and I said the area that she lives in. And he said he can't accept me because he has a Mrs. In anger my reply was "You have a Mrs? Well tell your Mrs to stop contacting my man on Facebook all the time!"
He asked what do I mean and tried adding me. Now I regret it. If he goes back and tells her, she contacts my boyfriend again he will know it's me because he knows I'm angry over this and suspicious as to what the hells going on between them.
Should I tell him what I've done or do I have every right to do this? Please give me advice
