Bhumi, Do you have any intimate friends to whom you can confide your dilemma and seek counsel? You need counsel from friends who are familiar with your quirks and can ascertain your strengths and weaknesses in case you are challenged on self-assessment. I am an online stranger. If I am critical of your situation based on your gleaned narrative, I may be mistaken for being uncooperative to your untold misery. Talk to your friends, disclose to them that you are choking inside with confused pain and suffering. Anyway, here is what I think. Broadly, everyone fits into 'resigned' or 'resilient' category when it comes to combat and decision making. I don't know which category you belong to. Resigned will succumb to the circumstances as they are averse to change with fearful reluctance or prolonged patience. They will fabricate reasons, they are prone to self-deception, they erect replenishable forbearance, and eventually they find happiness. Mind you, eventually they do reconcile to their status quo with reason or persistence and forge happiness. Resilient quickly adapt to willed situations. They may take foolhardy or unwise decisions, nevertheless, they don't mull over the past and readily embrace change. Good or bad, wise or foolish, they move on in life once they make up their minds. They are upbeat of their prospective future. Both kinds find happiness in their own ways. The confusion arises when you act maladapted to your strengths. If you are 'resigned' and you split up, you will explode your head with migraines on unrealized attempts to save your marriage. If you are 'resilient' and you chose to stick, you will wallow in your inability to adjust to the circumstances. What are you? Note: These are not predefined or preconfigured or immutable states or terms . I am using broad terms to drive a point home that you need to discern your ingrained personality quirk. Ok, this is why I stated that you need your friends because when online strangers don't mince words, they squander that agreeable charm in public. Let's be frank here. Just you and talking like buddies here after couple of drinks. Do you really think your in-laws would rue your absence? Your husband will find someone else, your in-laws will adjust to her, your kid will grow up, he will leave for college, he will tell his mates casually that his parents divorced, he will fall in love, his life moves on, your in-laws may recall you once in a while 'bhumi used to make nice halwa', that recollection will diminish over a period of time, your husband and in-laws will move on with their lives, they will still be fond of you with no bad blood, but eventually they will get busy with their lives, you are replaced, life moves on for everyone". Your guilt though heartfelt and genuine is misplaced. This is not specifically about your in-laws but in general how people propel themselves from a setback. Everyone moves ahead, one direction, ahead. I don't know your reasons for seeking separation. I won't comment whether you should proceed or recede. I wanted to comment on your subordinated inquiry and did that with (1) Know about yourself before you take important decisions in life (2) Don't assume that people will condole anyone's loss for eternity.
