Sex and Romance before and after marriage

So when my husband and I were dating he was so sweet, would do little things out of the blue just to tell me he loves me. I would get long texts, little notes around the house, flowers every now and then (I'm not a big flower person). We even did stupid things for monthly anniversaries a card or something silly but it was all in fun. All around he was so romantic, we had sex probably 5 times a week, if we went on a trip without kids it was multiple times a day, and there was lots of hugging and kissing and he just made me feel like he really wanted me and wanted to be with

me all the time. Now we have been married for almost 5 years, and lets say the romance has gone away, I'm lucky if I get a text saying have a good day. He hardly ever remembers our anniversary. I try to still do little things I still try to keep all that going but he has no interest in any of it. I have asked him why it all of the sudden stopped and he said that's what you do when your dating it doesn't continue afterwards, thats how you get them.Maybe I am just a hopeless romantic but I still want to feel like my husband wants me I want him to grab me and kiss me for no reason, I dont just want a peck on the lips when we are coming or going. I dont know what to do I feel like I married a lie.
