Hello Kiran,
I am not sure if this situation can be addressed properly on an open forum like this.....since quite a few aspects that you may not like to be out in the open could need to be discussed.
But to put it in a nutshell & very generically, always look for EMOTIONAL, MENTAL compatibility before you get into the age factor.....not whether you like his face or he likes your's. And age has NOTHING to do with emotional/mental maturity. I know of persons about your age, but with the maturity level of 40+ yrs-got to do a lot with their life experiences. I have also seen persons who are above 50 yrs but with the maturity level of 20s. And gender too has NOTHING to do with this.
Did you ever give this a thought: why do the elders suggest the woman to be of a lesser age than the man for marriage? Nature has made woman to mature [not just physically] much earlier than the man. Without getting into the 'why' of it, this leads to the situation where a woman of, say 20 yrs, usually ends up having the emotional & mental maturity level of a 24-25 yrs man. BUT REMEMBER there are exceptions for this too, like for every rule-depends on the life's experiences of that person.
So try to recollect your past interaction with him and don't focus on WHAT HE SAID/DID, but focus on HOW HE SAID/DID whatever he said/did & pl use your logical part of the brain to make a good guess on the WHY part [meaning why he could have said/did whatever he said/did]--I have seen many people-male & female- do the right things FOR THE WRONG REASONS...in a normal situation that could be OK, but in situations like your's it could be a royal invitation for future disaster.
Another way to get an indication would be use of Horoscope matching....I have found this gives a good idea of the POSSIBLE problem areas and then you can decide. Like for eg., suppose the man has a tendency [based on Horoscope readings] to spend excessively, the match would be compatible ONLY if the woman has a thrifty temperment....so on & so forth. In this, your choice of the RIGHT astrologer will be critical-just as your doctor's choice when you are ill. If the one doctor turns out to be a half-baked guy, you don't blame the whole lot of them...right?
Just remember that the key is to evaluate the issue thru ALL THE MEANS available and then do the Balancing act-NO METHOD IS FINAL-just as however well you prepare for an exam, there will always a chance you might not score well.....but by preparing well you are JUST REDUCING THE CHANCES OF GETTING LOW SCORES. All of them need to be used to get the final picture and then THE DECISION HAS TO BE YOURS.
Hope this is of use to you.
Rgds & All the BEST,
