So happy to hear your wanting to revert to Islam! Islam is truly the right religion.Trust me.  About your relationship with this Hindu guy, have you explained about Islam to him? Maybe you can tell him what drew you to Islam? There are also people who are saints in Islam,thus lead a spiritual life and as a Muslim too.But it needs plenty of practice, piety and Divine guidance.But you can see that Islam supports spirituality.So maybe he might be interested in Islam if you mention this.But don't guarantee him that he will become a saint.You should seek the help of Allah,firstly,then of true,trusted sheikhs or scholars. The benefits/pros of Islam totally overweigh the cons.If you know what I mean. I think, according to what I've learnt so far, a Muslim woman can marry a man as long as he is Muslim. Since he is Hindu,but not practicing,you might have a chance of reverting him too.  If he does, then you can marry him. But if he doesn't, then I'm afraid you just have to make your choice: Islam or him. Remember, what you choose will affect your whole life and your life in the Hereafter Maybe you will come across a better man in the future,Insha Allah, if you happen to choose Islam and he doesn't revert.If there are any good Muslim Scholars in your area, you can consult them. And pls bear this in mind: whatever happens, happens for the good of mankind. All is in Allah's Hands. The life of the Hereafter is much more significant and important than this worldly life. May Allah guide you and help you in your life. Insha Allah, I hope to welcome you to Islam someday! Hope you find this useful.
