Hi I'm really struggling with what to do with my horse and would appreciate other peoples opinions please. He is 20 years old, retired Arab gelding, I've had him for 15 years since I was a teenager. However due to work commitments and finances I put him out on loan 5 years ago (before he had to be retired). Unfortunately he came back to be earlier this year when I was pregnant. I didn't want him back as my life has moved on and to be honest I don't have or want the commitment of owning a horse again at this stage in my life. However I've owned him a long time so have tried to make it work and get back into it.
I now have an 8 week old baby and have admitted to myself that I have no interest in having a horse any more, I'm struggling to make it down to the yard regularly (luckily got a friend who has been helping me out while baby is small) and I'm going to struggle to pay for him over winter now I'm on maternity leave.
My DH thinks it's pointless having him and a complete waste of money when he's just a field ornament and I'm not getting anything out of it any more. He doesn't have any sort of bond or sentimentality towards him which is fair enough, he's never been into horses so why would he. He says the money soent keeping him for years more in retirement would afford us family holidays that we're missing out on and he has a point. But what are my options? Retirement liveries are more expensive than what I pay for him currently, I've advertised him in the past as for a companion/retirement home with no luck and I don't know what else to do with him. People have suggested having him PTS but although retired he's a happy and healthy horse. 
I'd really appreciate other peoples thoughts.
