yeah i also dont think arvi reunion will happen bc there's just too many issues to make it a pavitra rishta
1) the ovi arjun marriage. if arvi are pavitra rishta then how can arovi be really married. ekta will have to make something saying marriage was not real
2) purvi onir marriage- now their marriage has to be real since they went to the registrar's office and everything. and unless purvi-arjun got secretely married before, this is the only way to invalidate onvi marriage.
3)ovi pregnancy. so unless it turns out ovi had an affair, it means arovi consumated which just ruins the pavitra aspect of arvi
4) putting aside all personal opinion of pre-marital sex, pure relationship as dictated by the show means no pre-marittal sex. so arvi action once again takes out the pavitra aspect of the arvi relationship.
so i dont think there wil be arvi reunion. but if there is then i want an invalidation of the marriages w/ the other partners. no divorce or real pregnanacy by arovi. it has to be an extramarital affrair pregnancy. personally if it is arovi child, i hope purvi miscarries so that she can finally move on with onir.
p.s. this is not my take on issues of divorce and out of wedlock pregnancy in real life, and blended families-just the fantasy i wish to see in the show. in real things happen and its okay but in the show, i just want the perfect family u noe
