@IWannaGoToWALMART,
If you feel like a "family" then that is exactly what it is.
Alcohol made him kiss you, he felt like a dick after, he likes someone else and he was concerned about some other guy leading you on for 7 months, felt sorry for you and wanted to try to make you realise you are worth something, not nothing.
Just because a guy kisses you, it doesn't mean "oh, he likes me, yes," , alcohol played a part in this.
Don't do anything, if he chances his mind from this other girl to you, you will know about it as he will make it obvious to you..
There are plenty of fish in the sea and plenty of time to catch the right one for you.
