I wish people could just admit to themselves that they have feelings for others besides their SO. Not go around behind their back and lie and cheat and sneak to get s** or other things they need. It's pathetic and ruins so many relationships that don't need to be ruined. Humans are not built for strict monogamy, it's a recent Western idea within the last few hundred years or so. It is so normal and natural and okay to have feelings, sexual or romantic or whatever, for other people. Relationships don't have to be so strictly defined. Things can just happen as they happen. My partner and I love each other more than anything, but if we have a desire to see other people, all it takes is 1: safety and 2: communication! We have had no problems, and it's a wonderful drama-free way to live. I highly suggest talking with your partner. And if you can't talk to them openly about stuff like this, or h***, if you can't talk to them about every possible thing you would want to bring up to them... it's not a good relationship!
