Last Friday stbx moves out, Monday morning he's crying because he misses our daughter. Ok that's to be expected but now he wants to come over tonight to spend time with her. She of course misses him and is asking about him, which is totally normal and to be expected. How should I handle this? Should I let him come over, or is that just going to make it hard in the long run? I already said yes for tonight but I'm wondering if I should start setting limits? Our custody agreement is 80-20, so he agreed to have her every other weekend. I'm more interested in making this easy on my daughter than stbx, does anyone have some advise?

Oh and my daughter is four.
