Your thoughts required for Women based discrimination

I hope you all are doing well. Based on my experience as a men i have seen that if a wife of someone die in young age or even in older age so men get married again however if husband died than society is not accepting or not considering the act of Re-marry  of a women. 

I will welcome your thoughts on this society issue and also share what is the situation in your countries on this particular issue of Re-marry of women.
