I am sooooo jumping the gun on this and you have more work to do yet Reds but....
This is going to sound a little weird but I read an article once that explained it better than I will. If you are a single mom or just single and want to find out what type of father a man would be 1. see if he has pets, mainly dogs because they are more needy than cats (btw I would stay away from guys with alternative pets like snakes). 2. observe his interaction with his pets, does he hit or scream at them, show them love, ignore them.
The article went on to explain that seeing a mans nurturing side can be observed in his interactions with his pets and their interaction with him. When me an my WW started dating she hated any other guy except me. She would follow the kids around or WW. When I would come over she would sit and play with me and ignore them.
Also and I am assuming you already know this but don't just introduce guys to your kids. No at home Netflix and chill dates. Make sure you are VERY serious about the guy before you introduce them. Then it should be as friends. You and he are friends not BF/GF. Until they get used to him.
