Last relationship was emotionally abusive so I'm not sure if my radar is way out but I'm scared of getting into another bad relationship. A few examples from current DP:
He gets in my car (I've requested he drive as I don't know the roads where we're going and he likes driving anyway). We're driving along and he says "woah, petrol is really bad, never seen in so low!" I'm a little 
as I checked before I got to his house and it was well above the red. I said this and he says "no it's well into the red, almost to the bottom!". This simply could not have been true.
A bit further along he starts faffing with the heating control and says "phew that's better, you had the heating on full". This again is simply not true, I know this for a fact because I was boiling when I first drove to his house and remember specifically checking that the heating was off. I say this and he says "weird, because the heating was on full, I've just turned it off."
I know it just sounds a bit weird and not neccessarily abusive but I'm so scared it's all going to happen again I'm on major alert for any signs.
Another example was we were sat in a chinese and both ordered a chow mein each. He ate most of his and then said he was full. I hadn't eaten all day and continued to eat, really enjoying my meal. He was watching me intently and then started with comments like "Piggy" and "wow can't believe you're going to eat all that" etc which started to make me feel greedy.
So am I just being overly sensitive??
