What to get boyfriend for Father’s Day???

So my boyfriend and I just became official and moved into his house 3 weeks ago. I’ve been dating him for over 6 months though. He is currently supporting my 4 children and I since I recently lost my job. He’s only been involved with my children(I keep my adult life separate until I feel it’s right). He’s great to my kids and they love him... I believe he deserves some type of recognition on Father’s Day... but not as a father or step dad. I’m stumped on what I can get for him? Do for him? Have the kids do? Help!
