Will I be ok with the man marrying more than one or will I be able to marry someone who’s already married?

I have asked this question from myself a few times in the past and the answer to my surprise has honestly always been “yes”. This is how I feel now but it can change. According to my mum, it will change. Well I don’t out rule her argument simply because I don’t know what I will be ten years from now. May be I will fall way too much for the man to have him shared but I am by nature not possessive and in a very objective approach from where I am sitting right now I really don’t mind. It may however not be possible for a person to love all equally. Jealousy is inevitable.
As far as I’m concerned this is an amateurish argument. I feel that Islam recognises our needs far better than us. Nothing knows creation better than the creator. There may be men who need more than one partner and this can also be vice versa as we have seen in the past. Sometimes we just accept things without understanding their true gravity. Widows need to be taken care of but do they necessarily need to be married for the same reason? It could happen to any of us. What is our position then?
I try my best to put myself in the shoes of all parties concerned. Given a choice, a person would always ‘say’ that they want to be monogamous whether this by nature is true or not. My true feeling in my heart of hearts is that I would certainly be unhappy and torn to know that I alone am not enough for someone but I have thought about it to conclude that that - the idea of not having someone at all is better than to have him along with someone else - is wrong. This can of course vary from person to person. I think it is better to let the man free and have more than one; than to make him live the rest of his life with you but not actually want you or to make him have mistresses and the like.
As for the female I believe that the woman by nature is not polygamous. There could be various reasons why she could opt for more than one. One of which may be that the man fails her in someway. The problems arising from a woman having more than one partner (male) are far more complicated causing both physical and mental tribulations for children as well as other concerned participants.
Islam however lays strict conditions for a man to marry more than once. For example he must have the necessary means and resources to take care of more than one family. Of course in the modern days polygamy is less applicable and conditions are very difficult to satisfy. It is more the call of the mind than the heart that must lead a man to make such a drastic decision and he by no means must hurt his family when making such a move. In my opinion the need and the cause must be clearly defined and justified. Please see Jenna for more than this.
