It's funny how people don't realize that the little things they do define how people see them. Sometimes people notice the good things you do.. but more often than not, they notice the bad things. It's human nature to notice others' flaws more than their good qualities; they just stick out more for whatever reason.
It's also funny how when you first meet a potential friend or love interest, you try really hard to do things you think they'd like. But, for some people, as that friendship or relationship progresses, doing things the other person likes becomes less important. Some people just get comfortable and stop trying; they assume that person won't ever go anywhere.. so they shouldn't try to do anything to keep them around. Unfortunately, these people just don't get how life works. People like to be appreciated and they like attention. If they aren't receiving those things, they'll go look for it elsewhere. It's stupid for anyone to get too comfortable with someone they wouldn't want to lose. Once you get comfortable, things go bad. That's just how it is.
There's also that case where the person stops trying without really realizing it. This causes an even bigger problem because the person they stop trying for gets hurt and loses interest in them.. and the first person never even recognizes what went wrong. Is it fair for the person getting ignored and hurt to end the friendship/relationship? Absolutely. Even if the person who stopped trying doesn't realize what they're doing.. they're still at fault. They should be more in tune with people's feelings.. and they MUST have realized they weren't trying that hard. (Particularly if they used to do things for that person that they know they don't do anymore.)
So basically, if you want to keep people in your life.. pay attention to the little things. Make sure all your actions add up to what your heart wants to show someone. Because if your intentions are right but your actions don't show it.. well, to be blunt, that doesn't count for anything. Don't expect someone to stay around if your actions don't really show them that you want them to.
