silentsoul.. I agree with Lilith.. deep within you, you know the answer. However, you asked for a little input.. so I shall offer mine.

1) Neither of you should settle out of fear of not finding your "ideal".... settling only results in resentment and unhappiness.

2) A lack of desire to have sex with your mate is a HUGE indicator that there are issues that need to be addressed. Not addressing will only result in a continueing deterioration and ultimately no sex at all. There are REASONS why the lack of interest is there.

3) By description of your arguements, it would seem to me that BOTH of you have a problem with communication... and without communication the relationship will NOT last no matter the form. No man is an island, and if you can't share yourself, emotionally, mentally, and physically with your partner you need to consider other options.

4) IF you are serious about making it work, I suggest that you seek serious counceling (both joint and seperate) BEFORE getting married.

HUGS.. I wish you the best... PLEASE don't settle.. IF she isnt' the one.. SHE does exist..
