I try not to think if she likes me or not because I don't really see myself as a likeable person in general. So I suppose if I overthought it I'd convince myself she didn't.
What I do try to think about is that she must like me enough to have stuck it out so long with me, and show me the kindness and warmth that she does. It's her job to behave that way but still it makes me feel cared about to a certain extent and right now I'm happy enough with that. Infanct having the thoughts that she might just think I'm a likeable person enough to want to continue this with me does give me a bit of confidence that I can't be all bad.
