Give me another chance to fall in love and I will still fall in love with you. You have made my life so beautiful that I cannot see another world without you. You and I are meant to be together and I will always love you.
The further our relationship goes, the more I fall in love with you. I used to wonder if this love would ever get boring but now I see that you are the one for me.
To remain in love for a lifetime: listen actively to your partner, ask questions, give answers, appreciate, stay attractive, include your partner, give him/her privacy, be honest and trustworthy, tell your mate what you need, accept his/her shortcomings as who they are, give respect in all things, never threaten to leave, say 'no' to adultery, and cultivate variety in your activities to keep things fresh. You can never say 'I love you' too many times and you should say it every day. Even though you've been together forever it seems, you should still continue to 'date' your mate and find new ways to fall in love with them every. Single. Day.
