Answer :

In the name of Allah, Most Gracious, Most Merciful
Assalaamu `alaykum waRahmatullahi Wabarakatoh
1.      To have an extra marital affair is a major sin. That incurs the wrath and anger of Allah Taala. Such a person’s life is void of barakah and blessings. He/she should make tawba and Istighfaar and reform his/her life. Extra marital affairs do not invalidate the marriage. The consequence of such an evil may lead to injustices in ones marriage which may be considered to annul the marriage.
2.      Mazi is impure (najis). If it is lesser than the hollow of ones palm, the salah performed with it will be valid but makrooh. If one was not aware of the impurity, he will be excused. If the impurity is more than the hollow of ones palm, then the salah would not be valid. In such a situation, one should ponder as to when the mazi came on to the garment and follow that. If for example one concluded the mazi came before Asr salah, then the Asr and Maghrib should be repeated.
3.      The white drops will be regarded as wadi which is impure. Wadi invalidates wudu, not ghusl.
