I do wonder if the Americans get British humour, banter, winding people up, I watched the you tube in the end and they seem to get on OK? Some of it is a reflection of their relationship, you get the tit drink Kyle, he was the one to say something along the lines of oh, because that's all you think I deserve. He definitely has stepped up on his paternity, he kind of threw her under the bus, so he does the lions share while she lays in bed or watches TV, you go to the gym everyday, but as it turns out it's more to get Charlie out of her way.
I feel they are good friends, good parents but maybe not so much as a couple, that could be to do with the stage of their lives too, just that 3 little humans constantly take from you. We definitely had a roommate phase in our house I was permanently exhausted.
She definitely has daddy/men issues the 2 currently men in her life are the butt of all jokes, they are the ones that annoy her the most, she doesn't treat the girls the same way, yet she talks about projection.
