Seeking Alternatives: What are the good options in India for students who have taken PCM with biology besides NEET?

Hi Everyone, I'm 28M, IT employee, please do think from my perspective what am I about to ask. Since according to indian standards I'm already late for marriage. Now the thing is I've seen enough of failed marriages, not only in news but in own family and not everytime it was fault of the female part but I've seen good men struggling to handle themselves, few times their parents in jail. Thing is I won't be able to tolerate this kind of situation and I'm afraid of myself if I'm ever in this situation. My mother has sacrificed enough to put me through school and college and I do not wish to put her in any trouble because someone had a previous relationship which they are not able to forget or they don't like me then but get's married for the sake of it. I've never been in relationship and has been introvert throughout my life. Things that I've seen in my office and on news and at home have shaken my trust into anyone. A guy like me who use to trust anyone just because they say so is not struggling to even trust my own parents sometimes. Now please don't give me argument like not evey women is like this. I know but I just can't trust anyone and I've told this to my parents yet they insist on me being married. Everyone around me is just telling me how important it is to be married but I just can't. Since I'm only kid of my parents now my mum stopped talking to me a d I've given her my side yet she is pretty adamant on me getting married. Kindly let me know how should I proceed. Also I'm not interested even in being live in or having a girlfriend. I just don't know what to make of my life. So pretty confused, angry, frustrated and what not. Also my mother says that she'll have a thorough background check before taking things any further. I know how cute she is. She thinks everyone is as honest as her. Kindly guide me about how should I proceed since most of the people in my family is now not talking to me.
