I really don't understand why gay dudes are so lenient and quick to accuse partners and gays of being "insecure" and not "trusting" of their partners when their partners do things that for any ordinary straight couple would be considered shady as fuck. I mean it's Grindr. Even for the amount of people that aren't there just to fuck, its called Grindr- Gay Dating right at the top of the app. Everyone else on there wants to date and maybe 1 out of every 250 guys is legitimately open to being "just platonic friends" with an attractive dude they meet on there.
I mean if a guy was dating a girl and she was on, idk, what do straight people use? E-harmony? I don't know, some straight dating app, how the fuck do you imagine the dude would act? "Oh, that's cool, my girlfriends on this dating site, I have no reason to be suspicious/paranoid or feel insulted, totally cool. I'm sure she's just eager to meet friends on E-harmony/Straight Grindr."
He's looking around, waiting to see if someone better comes along. He ain't looking for friends bro.
Although I guess it depends on if you guys are just "dating" or if he's your actual boyfriend. And if he were your boyfriend, I feel like this kinda thing would have been discussed already.
