Hi Lee
I'm sorry you are experiencing problems with your divorce. I don't know what it is but divorce seems to bring out the worst in people. It used to be part of my job to do reports for courts on custody and access. The amount of frankly ludicrous accusations I used to have to investigate left me with quite a low opinion of the human race. And as for solicitors I tend to regard them as on the same level as pond slime.
The trouble is that it never actually goes away. It must 35 years ago that I got divorced yet I am still in contact with my ex wife. At first there was just simple things. School plays, sports days, meetings to discuss progress with teachers. The older my daughters got the more tricky things got. There was choice of GCSE subjects, then A level, then degree, then post graduate degree. There were major hassles when my youngest daughter decided she wanted to go travelling and my ex wife didn't want her too. The trouble is that you remain your kids father for ever. In fact there was hassle over just about everything. And you get to be involved in all of it.
My divorce affected me so badly that I went into a major depression. Things got so bad that I only just avoided ending up in psychiatric hospital. I hope you manage to develop a relationship with your ex wife that is half way civilized, it makes a major difference.
