Choices

Im new to this whole thing but theres a few things on my mind tonight.

I understand that marrige is a big thing and that it is meant for love, but please tell me why it is wrong for me to get married for the love of my child? this whole marrige situation would never make it so i worrie if i can provide food for my child or a roof over her head and if someone i did love can help me with that by marrige then why not? and if he is also making that choice for the love of his daughter then i find nothing wrong with it..... theres not much he can do to help his daughter and for the first four years of her life he will barley be around and that kills him. So he found another way to help her even if thats marrying someone not for love. Of course it sucks that the first time i ever get married its going to be this way but its time to put me aside and him aside and do what we can for our daughter.
And it really bothers me when people want to judge me for this choice i am making when that person has been through no struggles in their life have never been homeless.... have never not had food in their mouth.... who knows nothing about struggles. well I do and i refuse to let my child ever have to go through what i did growing up. and the worst part is that your bestfriend cant even open her eyes to relise whats going on or put her feet in your shoes for five mins and think about it.
