Please sit down and do a thorough brainstorming as to what are the things which make you feel connected towards her rather towards each other. Love is one of them.
Looking at the current situation decision of marrying each other should be postponed for some time.
I believe even if there is love its not easy to lead a Happy Life with daily feuds.I guess, calculate your Opportunity Cost of leaving or staying in this relationship.
Rest leave on time…..
