I told my 8 year old that boys can like boys. His father thinks I am encouraging him to be gay. Did I mess up?

A couple of weeks ago my son was making Valentine's Day cards for his class. He asked me if he is allowed to ask someone to be his Valentine. I asked him if he knew what that meant and he said it means telling someone you like them and have a crush on them. I asked him who he planned on asking and he said he didn't know. We were joking around and I named some girls off the class list. He giggled each time and said "no" for every name. After we cleaned up he asked if boys could ask boys to be their Valentine. I said that some boys do have crushes on other boys and asked him if he did. He asked if it was wrong and I told him it wasn't. He said he didn't know and we left it at that.He went to his dad's house this weekend and asked his dad if he (dad) ever had a crush on a boy. His dad told him no and asked where he got the idea from. My son said that I told him that boys sometimes have crushes on boys.His father called me pissed saying that I taught our son about being gay and now he wants to be with boys. He pointed out how our son only wants to be around boys, but don't all 8 year old boys? If he played with girls then I am sure my ex would say it was weird.How should I address this with my ex? I swear I wasn't trying to tell my son to be gay. To me this was an 8 year old being an 8 year old, but is it something more? Should I say anything more to my son or would it be better to drop the topic entirely? I didn't think it meant he was gay but is that something we should be prepared to hear from him down the line? I don't care if he is gay but I don't think he is. His dad will be upset if he's gay though and will think I caused it. via /r/Parenting https://ift.tt/2XxFwla
