Search Results: problem with friend''s boyfriend

We got into a bad argument a couple months ago after a weird period of us being really distant from each other, and he admitted to being so frustrated he thought about hitting up other girls, but never did. And since then he's been talking to this girl he knows 24/7. I'm not exaggerating when I say there is a notification that she messaged him every time I get a glimpse of his phone. But whenever I told him about how uncomfortable it made me he told me I was being selfish and paranoid and that she needed help because she's struggling with all these different problems and so on, and would continue texting her constantly. I had kept noticing the past two months or so, whenever he'd hand me his phone for whatever reason he'd always delete their DMs before handing it to me. And last night I had finally had enough of that and called him out. I was more mad that he thought I was actually stupid enough not to notice him do that so often then I was about him talking to her. And he kept listing excuse after excuse and kept saying he wasn't lying since they weren't doing anything and I have no reason to be mad and blah blah blah. But he is STILL talking to this chick non stop. And it really bothers me that he uses him knowing her from school (for less of a time than I knew him) as an excuse and will completely ignore my discomfort. I understand he's gonna have female friends and talk to them, I have male friends. But I don't understand why I'm in the wrong for being uncomfortable with him repeatedly crossing the boundaries of my comfort. He claims I'm violating his free will but I'm not asking him to drop communication entirely. I just want him to be mindful of how I feel and take that into consideration before going out of his way to start a conversation every day.

So, my best friend, let's call him Alex for now. I came over about 3 months ago to hang out after I was done my 2 weeks after coming back from my time. Alex explained to me that when we went to the beach together last year that Sam and he were flirting at the time, I was distracted, but he said I had told him that Sam had a boyfriend and not to get himself in trouble.

Long story short, apparently, when I went to get something from my car while Alex was in the water, Sam felt him and grabbed his Cough. He claims he was sure it happened and that he couldn't be making this up. He only brought it up to me recently becuase he was shy about it. Sam never said anything or acted like anything was up that day.

- One, Sam has been in a relationship for almost three years now. I know she loves her partner, so I'd be surprised she'd throw all that way so easily. However, she has a history of being reckless, so I don't really know.

-Two, Alex has a history of sexual misconduct. Sometimes, I genuinely think it's he doesn't realize how uncomfortable his statements can be. He recently said he wanted to watch me and another girl have lesbian sex for Christmas, and I told him that made me uncomfortable and that I had a boyfriend... who he's met several. He's also joked about taking my virginity when I was a little younger.

- Three, there was no one else there to confirm his story

I personally, I always think you should believe the victim, and I know male sexual assault gets ignored, and it's a big problem. He's my friend, and I care a lot about him. I've noticed since that day she's been more or less very cold towards him, even when he's the one being friendly. So, I have no idea what to do.

I was 17 at the time. My then HS boyfriend's foster mother (he became an orphan as a toddler) wronged me badly. She involved other people into this and tainted my reputation. Our relationship ended because of her. I lost a couple friends because of her.

Many years later (now that I'm married and with two kids), this year I received an apology from her. From the first time ever, there was no excuses, nothing to gain from (in the past she used to turn nice for something in return) and it was short. This is the message:
''(My name) I'm so sorry for everything. No one ever deserves getting treated like that. You weren't the problem. It was me. I don't blame you if you hate me. Once again, I'm sorry for hurting you''.

If it took you that long to know and understand what you did was wrong is it even worth responding to it? I'm not even on speaking terms with that past boyfriend. Is it already too late? I guess I can reply to her. Would you reply to a late apology?
