Custody agreements?

This is about my fiance's son so please bear with me. We are currently trying to set up an agreement with the mother of his son. She said we could do every other weekend and we video chat with him often now. We saw him twice in December but we had moved right after and just got back. Both visits she was present with her then boyfriend Jake we will say for the name. We were working at gaining their trust. I have called her and talked to her since she was pregnant so she could get to know me and be more comfortable. We could be on the phone for up to 2 hours sometimes just talking. He is 7 months old almost 8. He is crawling, almost walking..and it is completely our fault that we missed so many things as we waited for a dna, moved, moved back etc. Well now we had agreed that we would do short visits around her town first (she lives about an hour away) so to the park maybe to get some food then back for a few times before we took him overnight. Which was fine I understood why. Well now her new boyfriend Mason (as of feb) isn't comfortable with that because he sees him as his own (as do I) so we have to do 3 or 4 more visits supervised before we can take him to the park by ourseleves. Which means in reality probably a few more months of us not having him to ourseleves due to how well our schedules are allined. I have been around for a year in April and get no say which I respect because he is not my child even though I love and treat him as if he was when he is around. I can't say anything though. Does this seem right? He has been around for a month and a half and gets more say than his father or I? We never feel comfortable with the people she brings into his life when we do not know him and have no information on him. We were also informed we are not allowed at their house. We trust her judgment though so why can't he trust hers? Also the drive is only a big deal because she recently moved without telling us so when we moved back thinking we were close we quickly learned she was no longer 30 minutes away and in reality is more like an hour to 2. It drives us a little nuts knowing that as a baby he will forget us and the father son bond will have to be made over a weekend twice a month... It will be like passing him off to a stranger for him every time. It breaks my heart especially knowing so much of the time we get will be spent driving instead of playing or building the bond he wants with his son. I wanted to ask for a different schedule until he gets older and starts preschool or something like that. We were thinking switching every week.. I don't have a problem paying the child support we agreed to no matter the agreement. I will pay it from my check simply because it is for him. It doesn't bother me. We just want more time with him. Video chats are wonderful and I am so thankful she allows my fiance to have them but it just doesn't give the same emotion of holding him. Please don't say he is a deadbeat because there is a lot that is not explained in here because I am not here to explain our life or bad mouth just want some advice. We both cry seeing his pictures and cry when they leave or the video chat ends. We do love his son. More than anything in this world just don't know how to make it all work out
