She returned home and things were going good now I find out she is seeing someone else?

i hadn't seen this girl for some time than about a month ago she returned home to our area. she had always worked as a server at this restaurant and i'd see her there. so i've seen her there many times since she came home and we've talked and hung out there. but none of our conversations got into private things much and i found out why later on.

when i was there on Monday one of her co workers asked her about her " boyfriend " and what they were doing when he came up to see her this week. then she left as her shift was over and i haven't seen her since. and she won't be there Friday either as she and co workers going to see a concert in another city.

its also end of season at this restaurant as its more of a summer time patio hang out place and patio season almost over here as its October. so i'm not even sure how many shifts she has left there

i'm not sure who the boyfriend is but he doesn't even live here as she mentioned he was driving here in his car from where ever he lives. so its a long distance thing which is perhaps why she was able to hide it from me for so long.

she seemed to like it when i came in and saw her there so perplexed at the lack of honestly or why she'd rather date a guy from another city over me when i live rate here. long distance things usually don't even work out unless one of the people are eventually willing to move to where the other lives. so she's investing a lot of effort into something which may go nowhere over dating me.

i didn't go to the restaurant where she works tonight ( it was almost empty oddly for a Friday anyways ) but as mentioned she wouldn't of been there as she went to a concert with girlfriend's. figured i should find something else to do but came home early and rather go out Saturday instead but going to a country bar in another city not place she works
