Relationships; Expectations & Commitments

It’s been a while since I've not written anything.... Actually I was analyzing few things and haven't come to a conclusion yet but I've gathered enough material to put into writing..........
It's a difficult subject at least for me to write about. It's about Relationships, Expectations and Commitments that come with a Relationship.

When you get into a relationship with someone (any sort of. either friendship or love or whatever) some expectations and certain commitments always accompany it which varies from person to person but they are surely there.

It might be possible that both the guys in a relation are 100 % committed to each other according to them but the definition of commitment would be different for them and in this situation one can feel that the other one is not as committed as he or she himself or herself is.
Now it's a really difficult situation to handle as one's expectations are high and the other one does not expect that much. How to resolve this issue?

Someone will say that there is always a solution to a problem that is "Sit n Talk" but It might be possible that during talks the one who does not expect that much will come to know bout expectations of the other one and as the other one also cares for that person, He or She would try his/her best to make other one happy.

Now to keep the other one happy......sometimes the other person does some tasks or behaviors which he or she doesn’t want to do and that looks unnatural and if the one gets to know about it, he or she feels bad about himself or herself that due to him or her the other one had to change his or her attitude.

Sometimes people say “Let the time decide the fate” but when you are in a serious relationship like love…..You can not let the time overcome the situation n let the situation slip out of your hand.

I am still to find answer of this question..............Hope to find it soon.........
