No, I do not have children.
I will just ask. Not to get flamed or anything. I ask because it is something I CANNOT figure out, and it has been an issue since high school.
Let's take tonight for example... I went out with him again. When we are out, he seems to know everybody and is talking to everybody. I don't have a problem with him talking to people, but at some point I start to feel ignored. I either stand around or sit around and start getting really angry because I do not feel included. I try to smile and not look upset, but inside I am so mad. I realize he has a lot of friends, and he has a right to talk to him, but I absolutely hate it when he doesn't pay attention to me when we are together. I also was pretty mad because after he finally shut up talking to them, he spent a lot of time swapping insults back and forth with his ex via text. I ask seriously.... who is wrong here, him or me? I will admit that I stop being angry when he acknowledges me and says something nice to me. This is a situation where I don't know if I am being too needy or if I have a real reason to be upset because he isn't paying me enough attention.
In 6 months of dating I asked him to do very little. I asked him to go out with a couple of my friends not long ago. His response was "H E double hockey stick NO" because he doesn't like one of my friends that was wanting to go. So, yea... we didn't end up going.
I probably shouldn't bash him. I believe there is a very good chance that I am the one that is wrong here and I should not be so demanding and jealous.
Yes, and no. Yes, you are being overly needy to expect him to dote on you throughout the night. He should introduce you, but you need to keep up your side of the socializing (and this is coming from someone who socializes really badly. I have to push myself to be social)
The texting thing, IDK. It is hard to judge, because, honestly, you do seem to require a lot of attention, not to be unkind. If it is truly a constant thing, and he is spending his time texting her on the phone over actual nonsense, not stuff about the kids that requires immediate attention, then, yes, I would have a problem with it. I think it is rude to be on the phone constantly and unnecessarily when you are supposed to be interacting with someone. For instance, with my family the only time a phone is allowed at the table is if my husband is on call.
Him refusing to do something with your friends would be a problem. It appears that you do what he wants to do, but he doesn't reciprocate. Every person with a spouse or partner has a friend of that spouse/partner that they don't care for. Usually you suck it up and smile and play nice and just keep your distance.
OP. You really do need to do some work to figure out what makes you tick. You don't seem to be able to break these patterns of behavior in your life.
You really need to build some self esteem. Do something that gets you out of your typical rut. Go volunteer at your local animal shelter, food bank, soup kitchen, domestic violence shelter, hospital, children's charity. Take a cooking, knitting, dance, some sort of hobby, class. Join a book club. Find something and just do it yourself.
