Never think you have someone on lock, because there's always someone with an extra key. So many times, when we find Mr(s) Right, we lock down a union with them because we think we've found the right person. Most people know what to look for so when Mr(s) Right comes, they're able to lock it down successfully. Can you really lock someone down long-term? Yes & No. Yes: If you and the person have chemistry than I would become exclusive as quickly as possible because there's always someone waiting on the sidelines to take your spot. No, because as stated at the beginning: (S)he may not want anything serious; they could be wanting to play the field. While it's important to try and secure a long-term bond with a person, it's equally important to keep your guard up, because you don't know a person's values. Anyone can tell you anything that sounds good, and most people will eat it up like a buffet. When you have someone on "lock", they're essentially yours. In a romantic sense, when you lock someone down, they are your significant other.
One of my Facebook friends said something that made much sense: "Janea Robinson So the people who married to death, were they not sharing space and time? The divorce rate is high because people marry for the wrong reasons. It's hard to build anything on a shaky foundation." You can't build anything on a shaky foundation because the foundation can crack at any given moment. When it comes to relationships, it's best to lay the foundation as friends, and see where it goes from there. When I think about it, you are sharing space & time with another person by locking them down. You're allowing them into your world; they learn all they can about you & vice versa. Depending on the quality of the person, sharing space and time could be enjoyable or a nightmare. Not everyone is meant to share speace & time with you.
Couples that stayed married until death shared space & time; it was a matter of time before the death of one spouse. They were connected to each other, they didn't belong to each other. The following quote is from Babette Glenn: "IF married couples actually belonged to each other they would marry and stay together for the right and better reasons, not just for convenience." Looking at the divorce rate, she's telling the truth.
