I'm crushing on a couple and I don't know if it's wise to tell them

so i’m kind of in love with my two friends who have been dating each other for over a year. i have basically no emotional intelligence bc of mental stuff so i have almost no way to know how they feel about me, and i can’t really talk to or ask my other friends about it. i don’t know what to do about this and my feelings aren’t subsiding with time; i kind of want to tell them, but there’s a significant chance that it won’t go well and it’ll be weird, especially since i live with one of them

The good thing about knowing this about yourself - that you struggle with EI because of “mental stuff” - is that you can do something about it! Especially since you can’t talk to your friends about this, you should really find a therapist you can work on this with. There are also DIY resources out there - search for “emotional intelligence workbook” or “emotional intelligence DBT.” If you have a diagnostic term for the “mental stuff” you’re dealing with, you can also search for workbooks or other self-help resources with that term.

In general, my advice is usually to tell people how you feel, and let the chips fall where they may. There’s always a chance that things don’t go well and “be weird,” but if you don’t say anything, there’s a 100% certainty that things won’t go the way you want. However, every situation is different. Since you live with one of them, and living-space stress is one of the worst types of stress, you may want to be a bit more cautious. I don’t know what makes you say that there is a “significant change” that it won’t go well - is this couple explicitly monogamous? Have they expressed discomfort with that type of advance?

Only you have the full context to decide whether the risk is worth it. It might be worth it to find a polyamory-friendly therapist to talk things over with, or do some “pros and cons” journaling, or chat with a polyamory-support forum or chatroom, to try and work through all of the details. Best of luck!
