Provide the theme summaries for the following conversation: 

#Person1#: Honey, do you have a second? 
#Person2#: Sure! Are you okay? You seem a bit worried. What's on your mind? 
#Person1#: We need to talk. 
#Person2#: Okay. . . 
#Person1#: I've been thinking, and well, I think we need to start seeing other people. 
#Person2#: What? Why? I mean, we've had our ups and downs, and we have the occasional disagreement, but we're happy together, aren't we? 
#Person1#: That's just it, I'm not happy anymore, Tim. It's not you, it's me. I know that I can be hard to deal with, and you are a great guy! You are the type of guy that any woman would kill for! 
#Person2#: So, what are you saying? You're breaking up with me because I'm perfect? 
#Person1#: Tim, you are too good for me. You deserve someone who can make you smile and make you happy the way that you made me happy. Oh, I could say that I'll be all you need, but that would be a lie. I know I'd only hurt you, I know I'd only make you cry. 
#Person2#: Baby, come on. Don't do this to me! Whatever it is, we can work it out. Just give me another chance! I know that we can get through this, but we gotta stick together! Don't leave me. 
#Person1#: I can't, Tim. I hope someday you can find some way to understand I'm only doing this for you. I don't really wanna go but, deep in my heart I know this is the kindest thing to do. 
#Person2#: Laura. . . 
#Person1#: Here are your keys. I'll send my sister to pick up the rest of my things next week. I'm sorry, Tim. I wish you all the best, and I hope that one day we can meet again. I'll always love you. Goodbye.
