Is this a red flag?

I have a friend 'Tom" - he is aromantic. I'm posting this to ask for opinions on whether to stay friends with him or not after he made some uncomfortable comments. Also might worth noting that he has an older sister who is bisexual and has dated 2 women. We were all minors (including the sister) when the creepy comments started.

I was telling Tom about my crush on "Mira", this was my first time telling him about a crush before, and he didn't know I was lesbian. He was supportive and all, being queer himself, and didn't mind at all that I was gay, but still made some creepy comments and I'm not sure if I should stick around him any more. After explaining my crush on Mira, he suddenly started talking about how he couldn't wait for us to get married and smash each other every night, I told him that was a wierd thing to say and he went quiet.

After that first instance there were more creepy comments, while I was getting the courage to ask Mira out, he continued to suggest Mira and I get married, and I usually would awkwardly tell him that he was getting ahead of himself or stay silent. After getting rejected, Tom suggested trying to hit on a friend of both of ours "Rachel" who is straight but an ally. I suspect he said similar stuff to Mira after they rejected me based by Mira sometimes looking uncomfortable around him (the three of us always hung out and still do often) but they also hug or cuddle a lot platonically because Mira does that with most of their friends.

Not sure what to do tbh. Tom is generally kind of toxic and gets mad at me for stuff so I would probably stop being friends with him anyways, but I'm wondering if this is something to be concerned about. He is aromantic so I kind of feel like that would influence it, he's also kind of made a lot of sexual jokes with everybody, but in my case it wasn't even jokes, just comments

Edit: tbh I don't like the talk of "he's a man he's capable of being creepy" of course he is but other people are capable of being creepy too, i have received similar comments from women (both straight and lesbian ones) Thank you all for your imput

Edit 2: Thank you all for your input, this helped me a lot! I've come to my senses after some of the advice you game and approached him in person to tell him that I didn't want to be friends any more. I just realized that I should have done that a while ago; his reaction was switching from being sad and making me feel guilty, to mad that I was leaving, to happy that I was gone, to sad again over skype. He blocked me now (I guess I don't have to) I'm still going to stay in the same circle of friends with Mira and Rachel and a few others but try not to interact with him.
