Congratulations...I hope it works out for you both.
Now for a little bit of advice:
1) Never forget that the secret to keeping the feeling of "being in love" is to make sure you both feel good about yourselves in each other's presence. To keep a person feeling "in love" with you, MAKE SURE they feel good about themselves.
2) Never forget that it is OKAY to disagree with each other about things and that it doesn't have to mean that anyone is "wrong" or "right"...only that you disagree.
3) Always put as much effort into things as you expect from each other...ALWAYS.
4) Devise a savings plan and always pay yourselves (the savings) first. Keeping money tucked away for emergencies ultimately prevents many issues, a lot of stress and disagreements in the event of financial problems.
5) Always make time to go out as a couple. Once a week, at least. Even if it's just for a walk in the park...do NOT neglect the relationship.
6) Always listen and never blame each other to avoid any built up resentment and hurt feelings.
7) Start NOW getting the kids ready for this change. No matter how much Gio and the kids like each other...there will be big adjustments. The best way to minimize any stress for all of you is to sit down WITH the kids and make a plan together. Set up basic rules, expectations, talk about concerns and ask the kids to list what rules they can think of they should have and what punishment is appropriate if they break the rules. Kids have a MUCH easier time adjusting if they not only know what to expect but are included in setting guidelines. Ask them what their expectations, wants and needs are, too. Make the kids feel like they are part of the family unit and have input right from the get go.
8) Eat meals together with the kids at the table and use that time to talk about what's going on with everyone.
9) Choose one day a week as "family day" where you all do something together...even if it's just cooking out and playing frisbee or something. This helps a lot in raising children the right way. Keep the family connection strong.
Okay...done preaching. Again...good luck and if you follow my advice (especially regarding the kids) you should have as smooth a transition as possible.
