Is it normal that my husbands doesn't try

Been married for 18+ years. There's a lot of crap I've been through with him. My main thing is I have asked him to be more romantic, ask for attention, ask for affection private and public. the only time is when he is drunk and frankly, I don't want to be near him when he is drunk he acts like a child and too goofy. He flirts with other women, shows attention to them, throws me under the bus around our friends. I like sex but I barely when that's the only time he shows affection when he wants sex. I call it sex because frankly that's what it is, nothing slow no romance. He is too friendly with women. I tried dressed up, all nine yards tried, was going good for 4 months, but nothing rubs off on him, he does not get the picture. Yes gave him the best damn BJ and he'll agree. But tired of giving and giving with nothing in return. He would rather watch sports or news then bother with me. The sex is getting boring too. Oh I ask if we can try different places and other things just to add spice and we did which was very exciting. Playing games is a waste of time in my book, that is why I final tell him what I'm feeling rather then him guessing takes too damn long let's see 18 years. But now I'm telling him, it works for a few months then it stops. I'm just really tired of doing all the work with our relationship and rising our children.
