fight with husband. TTC & marijuana

I just had a huge and stupid fight with my husband.

Our situation is:

we’ve been TTC for about 3 years but he has bad sperm problems( according to several sperm analysis: low count, low morphology and low testosterone; even after Clomid treatment prescribed for low T and taking daily vitamins); and he is a chronic marijuana user, and since there’s mixed studies proving or disapproving the effects on sperm, he doesn’t believe it affects but he agreed to quit . He has promised me several times to quit but he just can’t completely and smokes sometimes which I didn’t make a big deal.

Today I told him I was concerned that during this holidays that he is going to be seeing everyday his best friend (who is a heavy user and always smoke together) It would be bad for him to smoke so much daily and that I wanted to share some articles I’ve read about smoking so much, even though he doesn’t believe I just wanted to share what I had just read. So he got very very angry on me for saying I wanted to share him information about it. He made again the promise that he wouldn’t smoke (a promise he oftens break) but prohibited me to say anything about “marijuana fertility effects” wich I sadly agreed but I droped a tear, as Im very sentimental. So he is also very mad because I dropped a tear and says Im never happy.

I feel really devastated because after that we argued for hours and now still angry with each other.

I really just want to feel support and love and comprehension. I love him because he is a very good man with me but this issue is breaking our relation.

Im crying so much now, I don’t know if I’m overreacting but I feel so broken and misunderstood and alone. 🥺

Please girls give me some advice or support because I feel so alone!!
