I 30f have full custody of my son Luke 8m, and have since he was about a year old. His father Mike 41m has supervised visitation and was in and out for the first year of our custody agreement, but completely vanished right before my son turned 3. Mike has bounced around, I’ve never known where he is and I couldn’t get ahold of him most of the time if I ever needed to. I tried to keep him updated on the important thing but most of the time I was ignored. Luke has never asked about his dad, doesn’t remember him, and I don’t bring him up because I don’t think my son is at an age that he can understand the situation. I figured once he starts asking about his dad, then we would have a conversation but for now he’s just happy and loved. Now Mike is moving back into the area and wants to be apart of our son’s life. I have no problem with that and setting up visitation. However, I don’t want to introduce him immediately as my son’s father, I want to wait at a minimum 6 months to make sure that he’s actually going to stick around. I don’t want to just throw a dad in the mix and suddenly Mike just rip that away by pulling a disappearing act. I don’t think I’m in the wrong but he’s not happy about that and I want to make sure I’m not just being biased. Mike did do me really dirty when we split but I wouldn’t keep him from being father because of that and I think that’s why he thinks I’m doing this. So WIBTA if I make him introduce himself as my friend? Also sorry for any formatting I’m on mobile.

Edit to add - this is a throwaway just because people know my main account

Second edit for some more clarification and more information. My main concern is Mike is incredibly flaky and is known to vanish after a couple of weeks, Luke is autistic and has a few other learning disabilities and has a very hard time with processing grief and loss. He struggled with the loss of my parents’ dog that died three years ago and will still ask when she is going to come back. Luke doesn’t ask about having a father, has no concern about not having one in his life, and I worry about the consequences of suddenly introducing one and then he is gone again. I only want Mike to be consistent before revealing who he actually is. Mike has been gone 5 years without seeing Luke and had only seen him 3 or 4 times in the 2 years before that. He has never been consistent in Luke’s life. I would love for him to be in his life, but I don’t want to hurt Luke.
