I've known him for the last 2 years, & I found his Facebook account & came across a girl who was commenting on his photos in a way that made it clear they're in a relationship. however, those comments were from 2 years before I met him, so I wasn't sure whether they're still dating or not. He has been telling me this whole time that he's single, not looking for a relationship & hasn't been in one for a long time. He would tell me he loves me & wants to date me once I move back to my hometown (cause I was living away in a different city for university & didn't see him often), but now I'm back here, and he told me that he's not looking for a relationship right now because he's stressed with work & is waiting to open his new businesses and all that before he focuses on a relationship. He said 'if it happens it happens, but I'm just not actively looking to get serious right now.'
At this point I'm sick of waiting for him, so I've decided I might as well just end it for good with him which will most likely happen if I mention that girls name (if they're still together). Should I surprise him by mentioning that girls name to make him aware that I'm aware of her & see how he reacts to find out if they still might be dating? should I message that girl myself and ask if she's still dating him & let him know he's been with me & telling me he's single? I just wanna make her aware cause I think it's unfair that if he's still her boyfriend, he's just getting away with this & she thinks he's an amazing guy when he's far from it. or should I just leave it & let her find out for herself later in the future?
