Relationship over Friendship

OK so I'm engaged to a wonderful man he is awesome in every way like he really is the perfect man for me he is a true gentleman and he loves and adores me we have always had a super close relationship and I'm so happy with him I'm also now 29+5weeks with our first child.

So prior to the engagement and pregnancy which both took place beginning of this year, I had an indiscretion I didn't cheat on him as in sex but I basically was in a hotel room with guys I went to the hotel because my friend didn't want to go alone(yes I know it was stupid to go) she was meeting up with a guy and I tagged along we had some drinks but nothing happened not even close then we left. Well my fiancé (bf at the time) found out I was at a hotel bc he saw it on my GPS one day and asked me I told him and he was angry and disappointed he thinks I cheated but I didnt, once I told him who I was with, the friend, he tells me that he doesn't want me to hang with her again that he can't trust us 2 together ever and when she comes around he always is reminded about the hotel situation. I told her what he said and she respected it. My main focus was getting his trust back so I didn't speak to her for a while.

It's now been 9 months since it happened and we don't speak at all anymore maybe a comment here and there on fb, but I miss my friend she wasn't my absolute best friend but we were really close, I'm planning a baby shower without her and it feels weird I know I was wrong but do I just respect my fiance and abondon the friendship or should I tell him I want to be friends with her again but I don't want to bring up the past. I love our relationship far more than anything I just wonder if I should mention it to him that I kind of miss her friendship or just leave it alone bc it might bring us to a bad place and we're sooo good now??
