Don't forget this feeling. When life wears at you, don't forget the feelings you have right now. How you are actually sad that he left to go hunting so you have to go an entire week without seeing him. When he's driving you crazy, remember how he makes you laugh at yourself and him like nobody has been able to before.
Remember this feeling right now, how you're beginning to get the feeling. THAT feeling. The one in your gut. The one telling you that you might be able to actually see yourself marrying this guy. Don't forget how much fun it is just kissing him, or teasing him, cutting his hair because he's not capable of doing it right himself. Don't forget the first time he gave you the remote, and told you to choose. Then vetoed Friends right off the bat.
Even in the fights, never forget how much he's making everything worthwhile right now. How he looked at Melissa and told her "She loves me." How he fits in with your dad and brother. How Jeremy actually said that he'd be pissed if you broke up. How cute your sister looked in his hat, and how comfy his hats are when you steal them. (2 so far!!)
He doesn't tell you how much he's fallen for you. That's not his way. Remember how you can see it in his eyes, when he can't wait to kiss you every time he sees you. The cute way he reluctantly admitted that Bauer is such a cute little guy. Remember the way he'll kiss you in the middle of the night, just because he can.
Remember these times, just in case the future isn't as great as it is now. Remember how wonderful he makes you feel, even when he's frustrating the hell out of you. Remember how instantly you felt that you were in this thing called life together.
Remember how you feel now, when you're falling in love with him.
