Baby daddy favoriting

Ko

So I think my baby dad is favoriting, he’s has a almost three year old son with his first baby mom and we have our 3 month old. He never post pictures or videos of our 3 month old because apparently his baby momma will get mad and not let him see his other son. Then today I just noticed how he took our son of of his background screen saver and put his other son on it, so his other son is on the lock screen and the home screen. This stuff is really starting to piss me off idk if I’m overreacting or what,
