confused....

well, still somewhat(lots) confused. In whole life, no or less interest earned on premiums for frst two yrs, have to pay interest on my own money if borrowed and less cash value if i die. Also so much of term insurance i've heard and read on the internet that its cheap and invest the difference. Would i be better off by investing my self if i have term or should i be letting the whole life insurance company do that if i buy whole life at higher premiums? please suggest if i've written clear enough, appreciate it. i'm 43 yrs, married and have two daughters 11 and 9.
