My relationship with my husband has been on rocky ground for a while - we've always had a stormy relationship, but since my daughter was born (she's nearly 3 now) he has been suffering on and off with depression and this has (arguably) led to some pretty shoddy behaviour on his part - he's lied to me repeatedly over and over about drug-taking, where he is, what time he's getting home etc. and is completely unreliable. I'm at the end of my tether with it all, miserable, and given he's not willing to change at all, we have decided to separate. He is moving out next week. He's a difficult person at the best of times and I'm nervous about the upcoming negotiations - mainly about how we co-parent our daughter and also financially. Should I talk to a lawyer? How do you know which ones are good and what is a reasonable rate to pay? I'm so sad and angry - I feel like I've tried absolutely everything to make it work, and I haven't gotten anywhere. I can't believe this is happening.
