Having a partner that drinks

I'm curious to know how other women are dealing with their husbands/boyfriends drinking habits. My bf is not a heavy drinker however, I am now 5 weeks (so new to this) and have no idea how to surround myself around people that are drinking alcohol. We used to drink all the time together at parties or BBQ/get-togethers but ever since I found out I was pregnant, I've stopped 100%. However, he hasn't and I do NOT expect him to or will ask him to. All I'm asking is for a little bit of consideration. It makes me feel so alone and him so inconsiderate to be drinking the same way he was before without even caring about the fact I have to sacrifice not only my body but eating/drinking habits now that I'm pregnant. It's frustrating. What do I do?!
