The Guy I'm Dating Wants Us to Be Exclusive. Do I Have to Agree?

9 hours ago

I'm a 20-year-old male college student who met someone new this spring. We clicked instantly and have been dating a few months. He visited me at college, and we're both living in New York this summer. We enjoy lovely dinners and each other's company with almost no issues, except one major sore spot.
I recently let him know I'm not interested in monogamy right now. Having been in a long-distance monogamous relationship before, the pressure and trust issues made me skeptical of that norm. I explained that because of my past, I struggle to feel deeply sexually attracted to someone I actually care about. We have OK sex, but it lacks the fire of casual hookups. I also explained that my interest in nonmonogamy was less about actively seeking others and more about lessening the pressure around potential lapses during travel or because of distance.
He seemed to take it all right, but I later discovered that within two weeks, he slept with three people without telling me — supposedly to avoid getting cuckolded or looking foolish. I haven't seen anyone else in the meantime, so now I guess I look foolish. When I confronted him about acting out of anger rather than communicating, he immediately blamed my original sin of wanting nonmonogamy, which he says is for 'hippies and sex addicts.'
I told him how I've seen relationships, including my parents', destroyed by infidelity and deception. I asked whether he would prefer a relationship filled with lies or one built on honesty — to which he said he would rather not be with me at all, which definitely hurt.
To ease tensions, I agreed to four months of exclusivity to see where we stand. I emphasized my reluctance to rush things, especially because I haven't felt deep love or trust yet and can see that he is much more into me than I am into him. Continuing, even not in my preferred way, seemed better than cutting off someone I care about.
But I'm still curious about nonmonogamy, especially while I'm young and good-looking and trying to understand which relationship styles work for me. Should I suppress my bohemian urges and go along with his desire for exclusivity or attempt another structured conversation about it? Am I too young for this to matter or is this actually the best time to test boundaries? Any thoughts on examining this situation and mending resentments before they spiral? — Name Withheld
