Can I save my relationship?

So, the gag is… I’ve been dating this guy for eight months. I like him loads, and we’ve even met each other’s parents (which was huge for me, since he’s the first guy I’ve ever introduced to my family). The issue is that he’s NM, and while that’s not a problem per se, the way he sleeps around is something I just can’t keep up with. This entire weekend he went AWOL. He told me he was going on a date Friday, then only texted me on Sunday. I ignored him (since he hadn’t texted me Friday) until yesterday. Today he texted me saying he misses me and pointing out our communication issues. I just wanted to let him know how all of that hurt me, but maybe I can’t. I’m terrified of realizing that maybe NM is not for me, but I can’t fathom being in a monogamous relationship either. What can I do?
