I'm glad you posted here because you really seem to want an unbiased opinion. Unfortunately, you may get lots of postings telling you to do whatever feels best to you.I have been married for 33yrs and I can honestly say that there are times during your marriage when you don't necessarily "feel" in love. Feelings come and go and typically shouldn't be the basis for a decision of this magnitude. I know it's not exactly a news flash...but marriage takes work..hard work. A really insightful article to read about falling in and out of love is found here on the Focus on the Family website. http://bit.ly/W8udf6
Really, you haven't been married very long. Also, since you mention having a child under a year old, would there any possibility that some post partum depression could be involved here? idk...just trying to help you think through it a bit.
