A lot of times, we fall into our comfort zone, whether it's not wanting to switch jobs, move household furniture around or cut off an unfulfilling relationship regardless if it's with the same sex or the opposite sex. I'll admit that I like things to be a certain way in my life. I don't move my furniture around often nor do I switch residences often...if I find something that suits me, I stick to it. However when it comes to relationships, that can be a different story. I can continue a relationship without any expectations however as we all know, people tend to push their beliefs on how your life should be. You'll hear things like "so what 'are' we", "what's next for us", "do you see yourself with me forever". And from the outsiders, you'll hear, "so when is the wedding date", or "when are you going have a baby".
No one likes to be pressured. That will only push someone away or make them not want to be bothered with you. You can usually tell the general direction of the relationship by how the person you are with conducts themselves. Or if you're like most people, you'll state your intentions in the beginning just to make sure the two of you are on the same page. Sometimes you can't control the feelings that will transpire between you and this person and things will become more serious. However, you can also tell when things are stuck at a plateau but most people ride it out, hoping that things will get better.
It all goes back to that comfort zone. People stay in relationships because they are comfortable. They don't think that they can survive in the new age dating world where men are the new females and women are the new males. When meeting a guy, I know what I like and there are times when I have to 'wait' it out to find out what he's really about. But if I find out that there's nothing there or if he wants more than I'm willing to give I tend to "let it go". No need in holding onto someone that isn't meant for you.
Another way that people don't "let go" is by continuing old habits. Whether it's cheating, or staying in a bad situation knowing it's not working out or even being an enabler in a relationship, all of these don't benefit anyone in a relationship. I have cheated and been cheated on, but at some point I had to make a decision that I wasn't going to be 'that person' anymore because karma is a bytch & it will continue to come back to me if I continued on that road. I know a guy who has a reputation for sleeping with girls who have boyfriends. He doesn't know that's his title, but that's how he is viewed. He's never had a girlfriend of his own that he was exclusive with and he's content on being the other guy while sleeping w/ females who are already involved. Then there are people who are attracted to people who need help. They feel obligated to make someone a better person & the relationship isn't based on love or a chemical connection, but more so as a good deed.
Either way you slice it, there comes a point when you have to know when to let go, and let be. People tend to think that holding onto something makes them stronger, when in fact, knowing when to let go and letting go is what makes someone stronger.
