new poster requesting support...

Hi all,

I'm sure that reading through all the existing posts will probably answer my question, but I thought I would try a more direct approach.
My situation iback follows:

I have a 9 year old son who means everything to me. His mother and I lived together in my hometown when he was born but when he was a year old she moved back to her hometown to live with her sister. We continued our relationship whilst we dealt with things and I moved the 280 miles to be with them. We then lived together for a further 6 months before I found out she had started seeing someone else and we split up. She moved in with her new partner and my son and we agreed that I would have him at least 3 nights a week, so I stayed in her hometown. Her partners involvement in my sons life regularly caused problems and her family eventually took my position and advised her that my sons interests should come first. Its important to note that I truly dealt with every problem with sensitivity and only ever spoke to my ex, we obviously had strong opinions and heated discussions - but never in front of my son and never with her partner.
When they split up a year or so later (my son now being 5) she almost immediately started a new relationship. This guy didnt move in but issues occured when her now ex found out. She also began to struggle with money and I tried my best to help when I could - knowing that it could mean the difference between seeing my son and not.
6 months later she then informed me that she had no choice but to leave and move in with her parents another 270 miles away, leaving all of "our" furniture and 2 months of unpaid bills at her previous address. Unfortunately there really was nothing I could do to help - my financial situation wasnt great and I was already giving £50 a fortnight - at the time more than I could afford (I didnt own or run a car, rented a room and walked to work, so that I had money to support my son for the 3 nights I had him)
I did my best to still see him, but could only manage 5-6 times a year when I got holiday from work, as it could take 6-10 hours to get to her parents.
In 2011 I managed to pass my driving test and get a car so was more easily able to get him, but still had to rely on time off work, so in summer 2011 I moved back to my hometown which was only 120 miles away from where my son now lived (this was a more financially based decision as getting a good job where my son lived was notoriously difficult). By doing this I also had the support of my family who would happily help out with childcare if it meant I got to see him more.
My relationship with my son has always been great and despite the interference of some of her family there has never been any question of my ability to care for him (1 sibling of hers used to try any tactic possible to suggest I wasnt a capable father).
Having moved back home I was able to see my son much more often, I now had all my annual leave, plus I could go and pick him up on a Friday night and take him back on Sunday (a 5 hour roundtrip - but obviously worth it!) I had to work my days off so that I could have saturdays off to do this as my job required me to work most weekends too.
At this point my relationship with my ex had become amicable and arrangements easy to make. Our only hiccup came near christmas 2011, when I asked in november if there was any possibility of him spending his first xmas with me and my family - only to be told that she had arranged to down to her sisters. I then later found out that she wasnt going with him, which meant that he wouldnt be spending christmas with either of his parents.

I can honestly say that I have done my best to support her and my son, including helping them move out of a flat they shared with her current boyfriend when they first split up, and back in with her parents.

Her parents and I have mostly got on well, but they moved back to my ex's hometown late last year, leaving her, my son and her partner in their current flat.

She recently informed me that she now has no choice but to move back down there, because she cant find a good enough job, so for the 3rd time she is taking my son 280 miles away from me.
I dont have parental responsibilty as he was born before december 2003 and we weren't married, and im concerned that my great relationship with him will be strained as I am in a similar situation with contact and will only get 5 weeks a year to try and see him.
I would really appreciate any help and advise as I cant help feeling that she is constantly running away from debts and I cant keep moving to be closer to my son in case she moves him away again.
Thanks in advance!
