Screw TV and movies; they aren't real.
As for your friends' fellows, well, so what? Everyone is different. Surely there are reasons why you are with this guy and not them. Romantic texting and whatnot is lovely, but you need to make a choice here. Which is more important - him or these missing texts?
And maybe the texts are
important. Maybe he's deficient in other ways, I don't know. Maybe it's evidence of a pattern of insensitivity or taking you for granted. Or maybe he's busy. I have no idea.
You did tell him to go and concentrate on his pal. He is doing that. He's kind of doing what you said he should. Don't get upset when he does. If you did not mean that, you should not have said that (you'd be surprised - or maybe not - at how literal a lot of people are).
In the meantime, learn to ask for what you want in relationships, and also how to make choices as to what's a priority. A lot of women are sold a bill of goods that a guy who brings flowers is oh so romantic, but maybe that guy can't pay the bills because he spends too much money on flowers. Maybe the romantic stuff is hiding in plain sight.
I have been married for just under 24 years. Want to know the sweet things my husband does for me? One of them is, he changes the hand towels every week. Seems silly and small, but I know he's thinking of me (of both of us). It's nicer, it's cleaner, and we probably don't get sick as often because he does that. It may not be the stuff of Harlequin romances, but it's one of the many things he does to show me he cares.
