I feel most awful for Rose in this situation. She is going to be the biggest victim out of all of this.

At least you and Jay have to awareness about everything... Rose, is walking her way into a miserable marriage and has no idea whats in store

I am happy for this.

>He's tried his tactics with Jay in the past as well and we're both sick of it (ex: tried to get with Jay's ex INSIDE Jay's vehicle, ditched him countless times on outings, etc.).

I don't know what the play is here.

Ideally, I would like to see Jay reject the wedding entirely. Not sure why he still is keeping him around as a friend. And the cherry on top would be confessing to Rose, why he is cutting Logan out and refusing best man. Its a wedding her cannot support.

Crazy this type of drama is surrounding you at 20.

Okay. My play is this.... after you execute u/KJM31422 comment

Jay, this is what Logan has done to me in the past. I cannot accept how you are in support of keeping him around. This shows me where your priorities are. I think we may need to consider if this relationship is a good fit.

Next... Rose, hunny. This might be one of the last few times we speak to each-other. But I cannot go silent. This is what I think of your relationship. You're going to be leading yourself into a trap. Logan is abusive to you. I am sorry but I cannot stand around and watch you dive into this marriage. It'll be hard to watch. I broke up with Jay because he is keeping Logan as a toxic friend. Before I go on my way, I just wanted to let you know my final thoughts.

And leave. Never look back.
