Not everyone who joins a hookup site intends to do any hooking up. That doesn’t make cheating on you okay cheating is not okay-if, again, he cheated on you. It’s also possible that he wants something in addition to all the wonderful sex he’s having with you-it's possible that what he wants isn't just a blowjob, but a blowjob from a man. It’s possible you do have a wonderful sex life. (I'm stressing those 'ifs' because some people join hookup sites to fantasize, not actualize.) If he went through with this- if you two have a monogamous commitment (I'm assuming you do) and if he got his cock sucked by some dude (and the jury is still out on that)-then you were definitely betrayed.
Before I go any further: I want to affirm your feelings.
