Thank you, everyone, for the supportive replies - yes, I thought my therapist gave some strange advice but at the same time it's always good to get a second opinion regardless of how good your judgment is..
Anyway, things are going alright with him for the moment

not exactly sure where it's going, haha. But I'm doubting he'll do anything horrible.. That's just my anxiety, I'm sure.
Exactly,
mote.of.soul !!! Thank you so much for your response. Racial profiling, that's exactly what I thought. I'm giving him the benefit of the doubt as you say

pray I won't regret this
Oh and it turns out he isn't Muslim, he's atheist!!
