Question: What is this thing you call 'obligation'?
 

I seriously, just don't know what obligations mean when it comes to relationships. There's this girl whom I have feelings towards to, and so her me. It pretty much started out fine, talking and calling and jesting with each other.

Then it started to be me who initiates the talks and calls, and she'll go,'why didn't you call/yada yada' when I don't. And I'm already losing interest at this point, and fundamentally ignorant about what should be done next.

So, how do you see obligation when it comes to a relationship with someone else?

First of all, you have an obligation to tell her you're already losing interest. Why drag it out even longer?

I agree. Be honest right away. I mean if you can't call her back for no apparent reason than you are going to have to say that it can't go on. I had the same situation a few weeks back. Even though I liked her, I didn't have enough interest, and within a week or so, she noticed and started complaining a bit, and I told her that I couldn't lie to myself or her that I wasn't interested enough to keep it going. In the end, I saved myself and her from having a lot more pain in the future.

I agree with what has already been said. The best thing to do is to be honest...not just at the start of the relationship of course, but all throughout. If you don't start with honesty now and the relationship progresses further, you (and possibly her too) would grow accustomed to beating around the bush when things are bothering you.

Let her know that the lack of reciprocity is bothering you. Your lack of interest seems to come straight from this absence of mutual communication.

There are many girls who like to have control of their boyfriends. I mean: they want to know where you have been, what have you done , then like u said: "why didnt u call" ,etc. If your girl is acting like that, you should take these people advices and be honest with her. I would add that you need to tell her that you would like more freedom and credence.
That obligation is some kind of ensurance for her that you won't cheat her. So you have to do your best in the relationship all the time.
That's my opinion :)
