its not selfish at all, i think you have been very reasonable wirral. i didnt mean to make it sound like i thought i had everything perfect, but i thought it might help if you knew what contact someone else had agreed on. tbh i hate the holidays aswell, i used to have awful nightmares for the couple of nights before my kids went away. they only stopped after i had ds3 - i think im too tired for nightmares now!
its never going to be easy but you do sound like you have your head screwed on right. the most important thing for me is that i carry on having a good relationship with my children when they are old enough to understand all this aswell as a good relationship now. my x has been dreadful, i have no idea how he is going to explain his behaviour when they are older.
if your x isnt getting legal advice, thats his problem. you can go to court if you feel it is necessary, it might make things easier (talk to your solicitor tho, i dont know your situation so might be wrong there!)
you definately need to have plans when your dd is away, even if its just planning to be hungover most of the time! i always got ill when the kids were with their dad, i think my body used the time to catch up with itself. now i have ds3 with dp i dont have chance to do that now, being ill seems like such a luxury!
i try to keep positive about things, if you tell yourself you are worried then you will be, if you focus on having time to yourself to go shopping, to the pub, or whatever you will cope lots better.
good luck xx
