We have been apart since my daughter was 6 months old she is now 4 and a half. He has had 3 new partners in that time, I’ve had 1 (which didn’t last long). His latest has been spending a lot of time with my little one and today my daughter got upset when I went to pick her up and she had to leave the gf. Am I totally out of order to get upset at this? I’d never stop her father from spending time her I just don’t want her taking my place
