Difficult Times

Well 3 months has passed, but the eagerness to go back to India has gone through the changes. It reached its crest and has subdued a little after that. It's not my home I am missing, not the Indian food. It's something else, rather someone else. It's hard to define the feelings, or give them the proper name. While everyone else would name it something but I would defer. Rather I am not comfortable in accepting that I have THAT feeling for her!
Oh! Shoot me, I like talking in jumbled words, and yes I won't take names. There is no point in that. Because what I am discussing is the feeling, not the person.
Coming to the point, is it rational to leave an opportunity of a lifetime for a friend. When you know, in return you can only expect some good time of around six months. Well good time means essentially some fun moments, weekend getaways etc. All of which you can have now too but alas not With your best friend.
I don't have the answer frankly, because there seems to be another aspect to it. What if the best friend really needs you? She wont ask you to come back only because she needs somebody to talk to. As she said she didn't ask for it even to her boy-friend. Of course she wont ask me too. But the fact is she needs somebody at her side, in some way or other. The decision I have to take is this, knowing that she needs some one close besides her, knowing that once this period is over, I may not get to spend time with her, knowing that not being with her for so long cultivates the risk of her making new friends (GOD forbid even a new best friend), would I still refuse the eagerness to go back and stick to the plan of making money for the future. A future that may be good or may be regretful. Because if you ask I am a person, who always regretted his actions in past. I have held back my feelings every time and have regretted about that some way or other.
I don't know what would have been the consequences if I had chosen to go by those feelings. I might have regretted them too. But there is no way to know.
The most frightening thought is what if I take the decision emotionally and I have regret about it later. It would be a disaster, at the least. And I may start hating her for this. That's not what I want to do. I love her, and want to love her till the end.
