My husband has an adult son (in his 20's), ex wife left him for someone else. My husband has always kept to contact & financial agreements & he has a good relationship with him, even more so, since he's been an adult. Ex wife blocked a lot of special moments, sports day, uni visits, school plays etc. SS constantly rings my husband with his problems, work, GF, family issues etc. as he has gotten older, I've gently prompted SS to think of including his dad in different/the nicer things such as seeing him at Christmas (ex wife banned this) & around birthday's etc. but I can't help but notice he still spends a disproportionate amount of time, doing some of the nicer things with them individually, as they are now also divorced yet relies on my husband for almost everything else in his life. I'm sure my husband is hurt by this but brushes it off, I'm starting to dislike SS (known him over 12 years) because I feel now that he's older & has his own life, he could do more to include his dad in the nicer things in his life.
