There's something wrong and my husband cares more about wrestling

My 16 year old has been in wrestling since he was in 7th grade. My husband was in wrestling but had to quit because he hurt his shoulder so he really wanted a son that could wrestle. We have a daughter who's our oldest which he wasn't happy about because he really wanted a son. Then our 18 year old son is disabled and in a wheelchair. He wasn't happy about that. Now our youngest son, he's a boy and he can walk and wrestle so everything my husband ever wanted. I have had weird feelings about him wrestling since he asked if he could quit freshman year. It was out of nowhere and he seemed upset. My husband said no and he could have a future. Be able to go to college. All this and I tried to tell my husband he's trying to live through him. But he continued and today he sat us down and begged to quit. He was in tears. I asked why he was so upset over wrestling and he shouldn't let a hobby make you this upset. My husband was angry and said this is his future. He can't quit. And that the season just started so he would be letting his team down. He was really upset and I asked what was wrong..my husband made a deal that he needs to at least finish out the season and not quit on his team so he agreed. I went to talk to him and ask what's going on and he can talk to me. He was trying not to cry and said he's just going to finish the season like dad said. I said if something is going on he can talk to me and he just rolled over and put a blanket his head. I went off on my husband and said he needs to stop trying to live through our kid and because of this something is wrong and he won't tell us. My husband is saying he's crying over wanting to quit wrestling means he needs wrestling to toughen him up more. This isn't about that. My husband is so obsessed with his dreams he doesn't seem to care and notice something is wrong. What do I do
