premarital relationship

Q: My question is that if someone is getting engaged and he she want to chat, is it permissible for the both and if not then is their any other way?

Q: I like a girl who is 17 years old and my age is 19 years. We both are classmates. I Would like to marry her. But I am not independent because I am still studying. And she also wants to study. I told her I will approach your guardian as soon as I finish my engineering. The problem is that her guardian is  hurrying for her marrage. And alhamdillah she has very good deen and taqwa. But when I said to her I want to marry, she said my guardian will do my marriage quickly. And alhamdillah we only used to talk. We never met alone. But now what should I do? Shall I say to her guardian that I will marry her after 3 years or as soon as I get independent? What should I do? She is telling me that bring your proposal before I get married. I don't want to show that I did love marriage. Pretend as if you didn't even know me before. Now what should I do?

Q: Why girlfriend/boyfriend is not allowed in Islam? Why we can't show and win the affection of a girl in order to be with her? Why only arranged marriages?

Q: I'm 27 years old. I'm basically from India and working in this country. My family has arranged a girl for me who is a local Muslim girl born in this country and she's 19 years old. I went to see her few days ago and it seems like both of us are interested in each-other. The families are happy too. Now what's bothering me about her is when I ask her about her past life, she said she has been in a relationships few times. And she did sleep once with a guy. (which I appreciate that she didn't lie or hide) Now after knowing that I'm like almost heartbroken. I also had couple of relationships and I was also engaged in all those haraam acts which I regret now to the core of my heart but I never had sex which I told her. I often watch porn and masturbate. And I only had oral sex. Please help me out. Are we both in a same boat? are we equal sinners? Should I go for her? I have seen she's really sorry about her act. And she's Willing to change.

Q: I am in love with someone. I think about that someone all day long. Neither I can study nor can I do other things properly. I am in great trouble. Please help me by telling me a wazifa to help me forget him.
