Well I don’t think fairness is the issue here, some people you might like are taken and some aren’t. And you don’t know them. They might be jerks

Feeling strong attraction to someone you don’t even know is often a sign of attracting “a familiar”. Familiar is typically another wrong man you go for.

Stay away from this guy, I’d not spend a minute guessing why their girlfriends aren’t there (work, kids, sick grandma, migraine or didn’t feel like it), couples don’t need to go everywhere together. It’s not wrong to socialize with anybody and everybody. But ask yourself if you’d come up to him and started talking if the girlfriend was there? If not, I’d say stay away. Bad news for you. You get attracted to wrong men.

I’d try to stay away from men for now. If you strictly seeking companionship from people, why must they be men? And men you are attracted to? You don’t like women’s company (don’t mean romantically but a companionship?). Dating now will be a disaster
