should I stop talking to this dude who has a cum wall??

I’m talking to this dude who has a cum wall… I know you’re probably taken aback right now but stick with me. Basically he would cum on his hands, lay there and throw in on the wall… he told me that he’s been doing it since junior high school. And that his mom would sometimes ask if the cum was coffee because it turned fucking yellow…..#－.－) “a genocide on my wall” is what he referred to it as. So tell me, am I talking to a fucking psychopath??? cause this dude has to actually be insane. I was soo repulsed I almost puked in my mouth. The funny thing is I was suppose to be at his house for thanksgiving. But I don’t think any dude would wanna invite a girl they’re interested in over with dried yellow cum on their wall…… I don’t even know what to do anymore. Also he’s 25 …. So this ain’t an immature teenager I’m dealing with. Which I think makes this even more insane. Anyways, wtf should I do… I’ve NEVER been in this situation before… ╥﹏╥
