AIO friends boyfriend made weird sexual remarks to me in front of her???

So I will go into more detail. My friend is my neighbor and she has a new relationship with the landscaper of our condo association. Basically they got off to a really weird rocky start in the first two weeks but ended up working it out and have been together for about 1.5-2 months now. About 3 weeks ago, her boyfriend works at a restaurant with good food and I am pregnant so he said he would bring me some of the food. I won’t get into too many details, but there are a lot of red flags with him to begin with. He is 15 ish years older than her, she is about 27 and has a son from another relationship, and he’s an alcoholic which is the worst of the red flags. I have already told her she should not be with him based off of everything she’s told me, and he may be nice but he is not good for her and what she wants for her future. He’s divorced and has an ex fiancé, and a lot more things I won’t say. Anyways, I went over to get the food and bring them a few treats I got when I went on vacation out of the country, and immediately I could tell he was intoxicated. First off meaning he drove to her house intoxicated. She told me he said that he can’t get through a shift with out drinking. She has a 4 year old and he’s hanging around him. Anyways, I notice he’s acting strange he seems drunk to me which was not okay to start off. We go inside and we start talking about my friends baby daddy and he is a horrible guy (she has told me she tends to pick the wrong type of guy) and I was saying how much I dislike him and some of these disgusting comments he had made about my friend, and I said “yeah just talking about him and all this gets me hot” obviously in an angry way, right? Well this guy took it as a sexual way “hot”. He says “oh you’re “hot”? You better get over back to your house and go fuck your husband right now then. Go over there and fuck him. Well, you’re pregnant again so you guys must fuck a lot anyways.” I was a bit speechless, I just said “well, I didn’t mean it in a sexual way. I meant it in an angry way” he brushed it off and continued to ask personal questions about my pregnancy, which mind you I am not friends with this guy at all met him maybe two or three times. He says “was it an accident?” And I said “no, but it happened a little earlier than we were planning. We weren’t as careful” and he blatantly asks “so what, did he not pull out?” Just very invasive questions for a married woman pregnant with her husbands baby and I don’t even know him. He then continued maybe 5/6 times to tell my friend “this good is ONLY for her. Not you. I specifically got it for her”. Which was really weird of course. He continued to make me so uncomfortable I couldn’t even look him in the eyes as he would speak to me. I kept trying to leave but he would keep talking to me. He said a few other comments that were weird but I can’t remember between my kids and pregnancy brain but they weren’t AS bad but everything together was just so weird for me. The icing on the cake was when I finally was like I can’t take this anymore I want to leave and told them I was going to head back to my place he said probably 6/7 times “noooo don’t go! Stay! It’s early, I like talking to you don’t go” in different types of ways. Which I’m like…????? You should want to spend time with your girlfriend, not me? I just felt so violated and uncomfortable. Am I overreacting with this?? And not just that, I brought it up to my friend and she pretty much just didn’t care. Makes me feel like she doesn’t care about my feelings. Isn’t a girls girl. Because if this happened in front of me with a guy I was just recently starting to see I would be like WTF??? Is that just me? She basically said when I told her I felt really uncomfortable and just everything was so inappropriate and in front of her, she just kind of pushed it aside and said “well I like a lot of things he does” like okay??? You’re okay with being with an alcoholic that talks to your friends like this in front of you? She asked if I thought he was flirting and I said I’m not sure but it was sexual and uncomfortable for me. she talked to him and he says he doesn’t remember much of what was done or said because he had been drinking and he’s super embarrassed but hasn’t spoken to me since. I have been avoiding him around the neighborhood too but she apparently told him I thought he was flirting with me and he denied it said he would never but even if he was he’d never admit it?? Idk I think she’s lonely and wants attention and he’s giving it to her and I am just really annoyed she didn’t even care how disgusting he made me feel. Am I alone in this is this weird or am I overreacting because I’m still upset please help
