"I'll tell my boy to come get me. Then you, then you start listening to friends, and then it, gets tricky..."
If my memory serves me correct, relationships are built off this thing called trust. Why is it so hard for people to accept their S.O. best friend when they're of an opposite sex? Is it really that big of a problem?
Insecurity must feel terrible, insecurity must be the issue. There must be a lack of security in your relationship that makes you worry about the best friend. As if they can take your spot.
If you can't trust that your S.O. isn’t cheating on you then you shouldn't be in the relationship. That right there solves the whole issue. Don't sit here complaining about the situation, you can simply exit it. You shouldn't be trying to force your S.O. to choose between you & their best friend anyways.
Now if you are the S.O. then I have a bone to pick with you too. Don't be giving off vibes that your best friend is more than a best friend. There should never be a reason as to why anyone thinks that you guys are more than friends. Pretty much, don't allow them to do boyfriend-girlfriend things.
Lastly, to make things real simple, don't separate the friendship from the relationship. From the gate, they should know of each other, they should be able have some sort of acquaintance.
Well, I guess my last point wasn't my last point. I prolly shouldn't have started it off with lastly. Welp.
To the best friends: PLAY YOUR ROLE. Don't be causing excess drama in their relationship or throwing shade, let them live there life as a couple. Don't be making it seem like your best friend is your S.O. knowing that it’s becoming an issue in their relationship. There's no reason why you should be a 3rd wheel, tricycling in their life.
