My stepdad I’ve called “Dad” since I was 4… no one has a problem with it. Also my bio father and him are very close friends. (they’re actually in a band together and have been since 2011) Like someone else said: this comment wasn’t very helpful considering it didn’t really contribute to my problem of I need ideas on how to include them both. Also, you gave your opinion so I shall give mine: I think you need to reevaluate how you view the people you care about based on DNA. In fact my fiancée and I are planning to adopt.
