This may be long so I can avoid drip feeding...
Ex and I split up when ds was 10 months old. Since then, I have moved away from my home town and am about an hour's train journey/hour and three-quarter's drive from the ex.
Ex has never been reliable at keeping up contact with ds, neither does he pay any child support (not relevant to the contact, but forms part of the bigger picture) as he doesn't have a job and insists that he doesn't qualify for JSA because of his wife's earnings. However, he also says that he can't afford weekly phone calls to ds unless we ring him and because of the travel costs has only seen ds once this year.
A couple of months ago, ds said he wanted to spend his birthday this year with his dad (it's on a Saturday so no worry about needing time off school). He asked his dad, was told this was a great idea and they were looking forward to seeing him. When they spoke again at the weekend, however, ds brought up his birthday again and ex now says that it's possible he won't be able to afford to drive/get the train down here to see him and/or take him back home for the weekend.
This is where I'm torn. On the one hand, ds's birthday isn't 'til early December and I'm sure that must be enough time for ex to save up for train tickets, bearing in mind that if you book in advance and get trains at specific times rather than open returns, it can be as little as £10. Then again, I'm not privy to nor am I interested in his financial comings and goings; if he says he's broke, then he's broke. For ds's sake, a big part of me wants to offer to pay for ex's train tickets each way so ds can still go up to see him for his birthday weekend, but when I asked my mum for advice about this, she was adamant that it's not my place to chase round after ex and make up for his lack of effort and that we should plan a back-up birthday treat for ds in the event that his dad does let him down (which he has done repeatedly for previous visit arrangements).
I really don't know what to do!
