My advice to TS is to solve the simple thing first. TS put in effort in house chores, after working so hard, while seeing the wife do nothing on her part. No sex also, maybe the wife is also super stress with work/post pregnancy until she also has no sex drive. Both of you need to talk it out to uncover the root cause that still remain hidden.

A tired mind and an exhausted body will make you feel or see things that is not there. Get a maid la TS, should be chump change with your 30k a month salary. Once both of you not so stressed with chores, can sit down do finance and future planning together with wife. Both of you need to share with each other that each remain committed to the marriage.

Lastly, investments and future savings is one thing, money earned needs to be converted to things that 'benefit' you in the now also. It may affect your future earning potential if you are too stingy on yourself (penny wise, pound foolish).

Also do spend your money on the family to 'convert' them into good memories that you all can look back fondly down the road. While you are saving for your kid's future education, no point also if he is raised in a warring household, sure will affect him emotionally and hamper potential.

All the best TS and consider yourself lucky that you are blessed with money, because it gives you some wiggle room to test things out.
