Before we can get any sort of commitment from anyone, we should all be open to other options.
No...people are different. I wouldn't date anyone casually or get involved with multiple guys at the same time because I'm just not built that way. Some people can do that but for me it would go against my nature.
Commitment goes both ways...if you are wanting the other person to commit but still dating other people it can send a very mixed message and put them off. There's this myth that if a woman makes a man jealous he will fight harder for her. That only works on men who want the excitement of a chase or a conquest...
and when that excitement settles down he may just move on to another conquest.
A person who wants a commitment and wants to put their whole heart into a relationshi
p is going to be more cautious. Seeing the person they care about casually dating other people is more likely to scare them away...not bring them closer.
