I met this guy. He seems super sweet and the vibe is great. After a week I realized he’s friends with someone I used to be involved with. The boy I was involved with wasn’t my boyfriend it was something casual for a few months a while ago. The new guy I met said they aren’t close they just have mutual friends. (His roommates are his friends 🤦🏽‍♀️Would I be wrong for continuing to mess with this guy? Is this a recipe for disaster ? He fully wants to see where things go still
