"Help! My Relationship Of 7 Years Is About To Sink" - A Female Nairalander Cries Out

hello house please help a sister out.. my relationship of 6 to 7 years is about to crash..
I Love my man and he loves me too.. he stands by me in all times and I do the same for him too in fact our relationship is a typical example of grassroots relationship.. but recently I'm beginning to get frustrated at his attitude or should I say our attitude towards each other.. which is why I resorted to you guys.. this is a faceless forum so I feel comfortable to share my worries..

in recent years I found out that our quarrels, dispute, misunderstanding and bitterness has drastically increased and it bothers me alot.. he quarrel more often this days and can even stay up-to a month without communication.. he complains about everything I do and that's me angry.. AM NOT A SAINT HERE cos he complains of my non Challentless too.. but this our constant quarrels and misunderstanding is driving crazy.. I've cried and ask GOd to dissolve us if it's not his will for us to get married rather than us fighting all the time. HONESTLY AM CONFUSED PLEASE YOUR ADVICE IS NEEDED. I love him and he loves me but we fight a lot.. our wedding is Sept ( still don't believe is possible though)..
