Can you help me out? Would you presume i don't like you if i did this?

I would not presume that they did not like me, if they had your condition. However, from experience I know that people who do have mood swings like that and occasionally act that way towards another make that person feel bad, and they instinctively feel like they should pull away from that person so that they feel good about themself too, because somoene having mood swings all over you does tend to bring you down, even though that was not the intention. Hope this helps.
