Ox fortune: I am a cancer born on July 5 1985

Hi, im planning on starting my business this may 2015, is that a good month to pursue my business?

Also im a relationshio almost 2 year with my partner also a cancer born on july 3rd 1987. I love my partner but he is very jealous, he annoys me alot and reminds me of my mother, (not in a good way) we fight a lot but were trying to make it work, I got caught texting with other people and also hung out with one of them(i did not tell my partner but I hot caught anyway) but my oartner still forgave me and i see the willingness to make the relationship work. is there a good future between us?
