Husband is not very vocal/out going with his feelings???

I’ve been with my husband for 6 years now, and from the get go he’s just never been the type to profess his love in a crowd of people or just pour his heart out to me. He’s super shy and reserved. I’ve always just been able to tell how much I mean to him by his actions and by how he treats me. He’ll tell me he loves me and all that good stuff but as for the more giddy/crush type of comments, those are few and far between. Anyone else’s husband or boyfriend like this? Sometimes I see other men posting these long sappy posts about their wife or commenting on their pictures about how beautiful they are and I get slightly jealous. Even if you know from the bottom of your heart, sometimes you just want to be TOLD, ya know??? He’s the best man I know and never lets me go a day without knowing that I’m loved, it’d just be nice to have some reassurance every now and then.
