I am the bad partner

[malificent7]

Dp is all anyone could want in a man...kind, generous , loving but with a complicated past etc, and only human.
I adore him but i can get snappy when annoyed. He is very gentle and i am quite a strong personality so sometimes i can override him.
He can take ages to get ready ...i mean ages...and then i get snappy...then i feel bad as he's so lovely . I feel like a bad partner.

It sounds like you need to learn how to relax. Have you ever thought about Yoga or similar? Running is good for aggressive types...I don't mean aggressive in a bad way....full-on, high achievers benefit from it.

Yes...just started running and yoga now you come to mention it. We do get on so well on many levels and he is like the perfect antidote to me. Id love to be more like him.
As for the high achiever thing...i am 2nd year into a very stressful course...i got a 1st in the first year but the workload has stepped up a notch and it makes me irritable and stressy.

Sounds a bit like everyone's life to me. Personally, I'd apologize when you feel you've behaved wrongly and just get on with it.

You have identified your bad behaviour and so you need to change it, apologising when you do it is ok, but meaningless if it continues.
He may be a good man, but at some point he wont want to put up with it.
