DD's dad walked out on us three years ago, when she was just two. He immediately moved in with a 17yo (he is 33), and within a year they had a baby. I stayed in the house we had shared for a year, hoping he would start making an effort to see dd, but he refused to commit to any regular contact or to give me any help, practical or financial. Two years ago we moved to live close to my family, who are very supportive. We have been to mediation 18 months ago to try and settle regular contact, but he failed to stick to what was arranged (one weekend a month).
Since then he has not really been very involved - he sees her every 6-8 weeks, when his parents drive the 80 miles to where we live to pick her up for the week and bring her back afterwards. She stays with his parents when she is there, and he goes round to see her during the day.
'Til I had dd, I lived as a traveller, and have decided to spend a year travelling with her before she really needs to be at school. I'll be 'home' edding her while we are away, and we will be travelling in the UK and Ireland, with the possibility of going to Spain later in the summer for 2/3 weeks.
As yet I haven't mentioned my plans to ex. In fact, I haven't seen or spoken to him since last May, when I bumped into him at a festival - all he said then was "Oh, hi" and walked off. I do not have a phone number for him - he refuses to give me one, as he shares a phone with his gf, who does not want me to have the number. I could phone his mother and get her to pass the message on, but don't want to because... 1) she is an interfering nasty old hag who I don't like and find it very hard to speak civilly to; 2) its not really her business - I had a child with her son, not her; and 3) she will heartily disapprove and lecture me at length on how irresponsible she thinks I'm being.
How do I go about telling him? Should I bother - given that he will still see dd every few weeks as usual - they will just have to pick her up from wherever we are, or I will take her there myself.
