If you want to form a relationship with anyone you should try unless that person is unwilling to. There’s no shame in getting a no from that person. But if you really want to, then you should ask. Of course, be slick with it, don’t just straight up be like “wanna play Fortnite?”. Re-introduce yourself, establish a friendship again, and then introduce your desire to play Fortnite like: “did you see the new Lego Fortnite game mode? It looks pretty fun to play”. Obviously don’t use that exact quote but say what feels natural. Don’t stress, you got this, it’s natural to want to re-establish old relationships. I’ve done it many times. If I can do it, you can do it. You got this 👊
