i am working with this guy for 2 yrs and go out for get together once in a while.recently we to an ofc party and he acted quite concerned around me.like the whole time we were dancing together he kept his arms around me (dunno why even when i wasnt drunk).later i was a bit drunk and ended up hugging him and almost fell asleep on his shoulder.he was very polite and later got me cab to send me home.however the next day i realized my mistake and messaged him saying i was sorry for being drunk last night.later i came to know that he was taking care only coz my boss asked him to check on me once in a while.i knew he was avoiding me n ofc and i even told him sorry for my behavior at the party and asked him if the scenario was that bad, to which he replied yes.now he hardly speaks and kind of joked around me in front of my boss saying he was asked to handle the danger (something like that).this really embarrassed me and told him that i already said sorry abt the incident.he says he was just joking but somehow i feel his nature towards me has changed.am i over imagining things? he knws i have a bf.does this make any diff? or sud i forget everything and move along? guys please help me out here, i am so confused and why is this bothering me so much?
