I wonder if the OP was looking for suggestions to snare her man for good? Oops on the BC? Sorry, that's not funny.
Being a lazy, halfasses boyfriend in the past and all: to want to marry somebody should mean that you want to share everything you have to offer to that other person and only them. While we don't spend every second together, that time that is spent together is the most blissful and the most looked forward to. The feeling of growing together and strengthening of the bond each and every day, and that indescribable feeling that comes with it continues to grow.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
