Backstory- Dated a guy for 3 weeks in Feb '16, I ended it as he was really flaky. We hooked up again in May and he told me after he'd had sex with my twice that he was dating a girl but it was early days and they weren't exclusive. I was simply after a FWB and casual situation so thought nothing of it. That was until he told me to use code words when I was texting him Incase she was around and saw them. I realised this wasn't someone he was seeing 'not exclusively' , confronted him and he admitted they were together and she had a low sex drive and wasn't exciting in bed, hence why he looked elsewhere.
I asked if she was aware of this and she wasn't, he was cheating. I ended it there and then. Felt no love lost and wasn't exactly heartbroken just felt I had a lucky escape! I strongly urged him at this point to not lead this girl on and be honest with her. Fast forward to September and I'm now dating an amazing guy and really happy. I receive a text off this guy and start wondering why he's speaking to me...he was wondering if I was up for a 'quickie'. Informed him politely I'm happy and asked if he was still with this girl, turns out he is and was looking round for a bit of fun.
*I've been cheated on before and my heart truly goes out for this girl. She seems really into him on social media yet he's messaging me and probably other girls. I'm also concerned for her safety. When with me he stated he wasn't sleeping with anyone else and we didn't use condoms, I got an STD test immediately after I found out that wasn't the case. Fortunately it came back clean for me.
*I'm in a dilemma. As a fellow female and woman, also as someone who has had a boyfriend cheating on them...it's heartbreaking and I wanted to know. Despite it being hard to hear, I came out better the other end. I want to show her the screenshots and let her decide what she'd like to do with them. I have no emotions or feelings for this guy at all, he's not a friend of mine nor do I like or dislike him. I just know what he is doing is wrong.
*On the other hand- is it my buisness? I'm happy in a relationship of my own, why is it my buisness to meddle in their affairs?....what should I do?!
