Search Results: what is first base in dating relationship

I like a guy from work of three years both managers/good friends.
In the past I felt he liked me but I was taken or liked someone else.
When I was overseas last year I set him up with my best friend, he got to second base one night nothing more after that she now lives over seas.
He was causally dating someone beginning of the year they occasionally met up but nothing came from it. He won’t discuss this with me since they ended things [I was first to know] [but he talks to others about it].
He texts me picture memes often in relation to personal jokes between us. This has stopped recently in the last month or so.
I feel there is sexual tension but the more I feel I am flirting he is backing off.
Despite that these are things below to suggest he may like me.
