What's up!
Well, I can relate somewhat...similar boat as you, except I didn't have strong hints from mine...but one or two....in that, she didn't want to make similar mistakes that she had in her past..."move in with a guy", etc.
Gotta look into yourself..and your own heart for this.
With my situation...this was my second chance with Michelle...as her and I had known each other for around 8 years....way back then when I was single, she was with her ex..but they were on their way out...so all we did was have smiles, eye contact, jokes...that sort of "flirting" stuff. Then right when I started dating my ex wife...I was on my 3rd date or something..on my way over to her house..when Michelle calls me...she was out with her sister..and made her move on me. However..being on my way to the 3rd date with my ex wife...I kept going...spitting out some excuse. Man..hindsite...if only I had turned around back then and went to see Michelle.
But...fate...about 14 months ago..she heard I was divorced for a while...she was single, gave me a call.and here we are now.
Honestly...I didn't figure I'd remarry for a long...looong time....if at all. But....the relationship that grew with Michelle...we became like siamese twins....inseparable..hated to be apart from each other. I found myself more into her than anyone ever..in my past. I decided to give love, and marriage...one more chance. Hey...3rd time is a charm, right?
It's something you have to look deep into your heart for. Don't let a marriage that didn't work in the past ruin things for you. Learn from it, look at your past marriage..look at yourself....see what didn't work, and do your best to see that you don't repeat that pattern again. You're young, people make mistakes. Learn from them...and in learning to not repeat those mistakes that contributed to a failed relationship in the past...you'll be that much better in your new relationship. You'll have that much more drive to make it work.
Things that need addressing before you get married? Usually easy to figure out and discuss.
