Have spoken to exH today and found out that he is not attending DS' birthday party (even though he said he would to DS).
Tbh, from my opinion I am quite glad to not have him there as it means I can enjoy the day with DS without having to deal with exH but I just feel so sad for DS as he hasn't seen his dad since November and now we have no idea when he will see him next.
He has said that he would send money for his birthday present (as he did for Christmas) but that isn't the bloody point! DS would much rather actually see and spend time with his dad rather than have £20 put into my bank account!
Aibu for being so worked up about exH letting DS down again and really want to be able to get over being so upset about it?
