We got along great on Friday but on Saturday she showed up with another guy?

i ran into this girl at my local pub on Friday night that i hadn't seen there for a while , i talked to her for a bit and though we got along really well. she seemed glad to see me as it had been a while since we saw each other there.

but then on Saturday she reappeared at the same pub but was sitting at a table with this guy , i don't know who he is , no one mentioned anything about him to me the night i talked to her , she never told me she had a boyfriend. and on Saturday she didn't even like talk to me , she came near me and talked to some other people we both know in common but didn't say anything to me.

did i come on too strong on Friday so she decided to scare me away by showing up with this guy? i'm also not sure who he is , i do follow her online and never seen anything that features him before or a mention of him
