M27 - want wife with no past, iam i wrong?

Iam well settled and come from middle class conservative family. So first of all i domt have any past so iam also expecting same while looking for brides. Now my question is expecting this is bad? And i have some reason behind it like:(ima not talking about just girls here)

1. Seeing nowdays how girls/guys dont forget about their ex and sometimes marriage broke if they come back.
2. Some people just do marriage to unburden their parrents and continue their affairs after marriage.
3. I think love is one time thing if she/he has already in love and brokeup will she love me truly?
4. IMO if people have beend through multiple relationship Then its easy for them to break another relation..
5. Not actually reason but judging based on someone's past is okay? Because that thing is matter to me. And what else should i thing while doing thiz?

So whay do you think of this iam thinking in wrong way? (Ima not good writer so if u got confused somewhere plz let me know).
