I'm not sure what my AIBU question is here but I'm incredibly concerned
This is INCREDIBLY unlike my partner. He goes out a handful of times a year, usually in the afternoon for a few pints and is back in the evening. I'm completely and utterly stunned.
We did magic mushrooms together once 3 years ago. It was a pre-planned thing. We were early 20s at the time and didn't have any responsibilities. We'd made sure we were both off work the next day, and ensured we were in a safe environment. It was relatively harmless, we watched a film together and had a laugh, slept it off and that was that. Though overall the time we did magic mushrooms together was okay, he did present a bit of paranoia about a neighbour getting a parcel delivered. I'd taken a smaller dose than him and had to reassure him and sort of babysit him. After that we agreed it had been a one-off bucket list thing whilst young and that we had 0 interest in doing it again, especially since we had future plans involved building careers and having a family.
We also had a conversation again when I got pregnant with our planned baby that we'd never take the risk of anything like that ever again as the risk of having a bad reaction and resulting mental health issues is far too great when we have a child. He usually really has his shit together and is going for a promotion and we're in the middle of a mortgage application.
I'm now 8 months pregnant. He mentioned that his workmates had invited him out to watch the match tonight. He's not interested in the football and told me he wasn't going to bother. A bit later on he said he may just pop out for a few pints and enjoy the sun and he back for dinner. He booked his taxi, went off at about 3pm and I didn't think anything of it.
6pm I get a text saying "In the taxi on my way home." I replied and told him I'd done dinner. Honestly didn't think anything of it. He then said "When I get in put me to bed". I was shocked because I hadn't expected him to get drunk, he works at 7am tomorrow in quite a dangerous role that involves driving heavy machinery and they have a rule that you can't be drunk within a certain time period prior to a shift, and they do occasional drug and alcohol urine tests on employees without prior notice. I asked him how many pints he'd had an he replied saying "mushroom".
I let him in the house and he was laughing and giggling and started hugging me and saying sorry. I had to push him off me because he was unsteady on his feet and I was scared he'd fall on me and the bump. He told me "It's just about to kick in". I supervised him into bed and have now left him to it.
I am so fucking angry at him and feel like an absolute mug. This really is so unlike him, I cannot believe it. How can he be so stupid? What if I were to go into labour? What if he gets urine tested tomorrow and sacked? I'm incredibly stressed. We have no food in the house and I had been planning to go and get some but now I can't leave him. I'm hoping he stays asleep but I know usually on mushrooms you can't sleep. I'm concerned he will get up and start wandering around the house.
I feel like such a fucking mug for never considering that he would do this. I honestly don't think he's lied and pre-planned it, I think the stupid twat has been taken in by peer pressure from "the lads". I can't believe I'm pregnant by someone like this. I feel like once he comes round he's going to play it down. I had our health visitor appointment the other day and she had asked a general box-ticking question about whether anyone in the home is a drug user and I'd said no with no hesitation and now I feel like a liar. I'm devastated.
