Mother in law probs 🙄

So me and my husband have been together for over 4 1/2 years been married for 3 months. Don't get me wrong I love his mom.. But there just a tiny issue when it comes to us having kids. See me and my husband don't drink, smoke or party.. I've never actually drank a thing in my life or smoked anything in my life.. I was raised different (not sheltered) just raised different than he was. My parents didn't keep me from the world I just choose not to do those things (I'm 22 now) I've never had the want to want to drink or smoke or party.. Not that I'm a boring person I just don't do those things! And not saying my family was perfect either, they didn't drink and do drugs but it still wasn't always the best environment either with my mom and dad always fighting.. Anyways, well he drank a little and smoked cigs before we got together and then quit when we got together because he knew it made me feel awkward.. He just loves me that much lol well his mom is a Huge drinker, smokes pot, party's every weekend.. Hangs out with all his friends and sleeps with a few of them! She's never had a successful relationship.. My husband was a one night stand baby and his dad has never been in the picture.. just a really immature person to me.. When me and Gunnar (my husband) got together I felt soooo out of place due to the fact that I've never been around that type of person specially a mom who lets their 16yr old drink and smoke ect.. So it threw me off then. Well when she found out he quit drinking and and stuff she flipped her lid saying I was no good for him.. Ect... We got over that and now 4 years down the road and married were talking about having kids... I told me husband and we BOTH agreed on raising them right and basically not being AS laid back as his mom was when he was young. And he himself said that he didn't want his mom around the baby if she had been smoking pot. Specially  can't can't keep him/her if she's going to do it around it. He told his mom that and I've never seen a grown women act the way she did... Saying that it's unfair and how we were just awful people and again how I was controlling everything.. You'd think she would be proud of us for being such adults but no. She's so jealous of us.... Always has been. It's sad that her 21 yr old son has had a more relationship, an amazing job, marriage, a house and everything else.. She still lives with her parents, doesn't pay bills and works at a gas station because she can't pass a piss test for a nice job and she's 42 yrs old... Is it wrong of us not to want our future baby in that type of environment????????? Is it wrong of us not to want our baby exposed to pot????he said growing up he watched his mom do drugs, hard drugs.. Wagged around place to place living with crack heads.. Luckily his grandparents stepped in when he was 6 and raised him!!!! And not to brag but thankfully I came in his life when I did and helped him along the way. He is such an amazing person and you'd never know if you'd met him how much a mess his life used to be.. I'm so thankful for him and so proud of him and I want us to have kids and raise them and encourage them to do the right things... I'm so tired of this backlash from his mom about this it's seriously depressing 😢 and my parents arnt perfect but they understood when I told them no fighting and arguing around them with their young and I told my dad no smoking cigs around them either and they completely understood because it's going to be OUR baby! So what we say matters.. Right?? Nope, not to his mom 😒
