So anxious Vday around the corner

My boyfriend and I have been together just over 4 years. Since then we have lived in 3 different homes, been to vacation to Mexico and Hawaii, birthed one child/miscarried two. We have my two kids from first marriage. I’m 27 and he’s turning 39 this year. His brothers been married a very long time & the few friends he has are married. We always talked about marriage for years on end. I basically told him I wanted marriage and/or children 2.5 years ago and that if that wasn’t the direction we were going then I needed to know. We have had numerous conversations so communication is not a problem. A couple months ago we looked at

Rings. This is not the first instance... A few weeks ago marriage came up and I reiterated he is the one and I’m expecting marriage this year as he was showing some insecurity when talking about him being the one... Valentine’s Day is in 2 days and I’m freaking out. He’s the type to give gifts on holidays..

Don’t know if this is good or bad but I have 2 promise rings and from Christmas his late moms opal ring that he gifted me. He told our middle child a few days ago in a heart to heart talk (they’re real dad isn’t in the picture right now) how much he loves her and mommy and is gonna make mommy his wife. He said it with seriousness and it was reassuring.

I’m so terrified he won’t follow through and I’ll be heartbroken. Money is not an issue whatsoever. He knows what I like. I’m just SOooooooo scared and nervous.

I love him most importantly but this will be a true testament for me...
