Need Advice

My husband and I have been trying to conceive for almost a year. We were put on fermara in December and I got pregnant with a ectopic and lost my tube in Feb. we went to a different doctor and tested my husband and I. My husband has a low sperm count and my raw wuality is great. They recommend my husband quit drinking and stay away from baths. We did another round last month and I take a pregnancy test again on Sunday if I don’t start my period. My husband started drinking again last week and is drinking too much and even got mean last night. I cried, I love him and I told him no drinking till we get a positive but he’s ignoring the doctor and making. Up his own rules and saying it’s not going to hurt. Then when I say you have a low sperm count he gets mean and says I’m blaming him. I don’t know what to do. I’m at a loss and hurt, upset and confused. Any advice would be great.
