@asdsasd,
This is FWB.
It's not supposed to be exclusive.
This is reason #850,223 why FWB is THE worst way for people to relate to each other. It is inevitably uneven. One person catches feelings. The other doesn't.
Don't tie yourself up in knots trying to give this guy your loyalty when he didn't ask for it and is most likely not reciprocating.
You met a pleasant man who you fucked a couple of times. And that's it.
If you want more than being an occasional **** buddy, then meet other people.
And for God's sake be 100% up front about what you want. If you want a relationship with feelings, time, dating, etc. Then. Say. So.
This guy told you exactly what he wants.
Learn from this experience and start doing the same.
Life is a lot simpler when you do that.
