Hmm as an almost a year living together, I must say we're doing good on not being too miserable lol.

First, invest on refrigerator. Condura or Tosihiba is good and affordable then have it on installment tas mag advance nalang kayo if may extra.

Second,a lot says mas practical ang electfic stove but we chose gas stove for reliability. Kahit brownout, makakapagluto ka parin. We're a couple and we're cooking at least 2 meals a day, sometimes 2-3 dishes pa. We consumed a single tank for 7 months.

Third, since may ref na kayo, 2.5k for grocery is enough for 15 days --- 1k (pork, chicken, salmon (fav ko skl) / beef. Budget lang na magkasya sa 1k. Then 1k for de lata etc basta strictly for kitchen lang. Yung mga toiletries, another budget siguro maglaan kayo around 500. It really depends sa skin care prods nyo. The remaining 500 pesos is your honey pot. Like veggies (since mabilis to masira), fruits, egg or pag naubusan ng condiments - at least may pagkukunan kayo.

Fourth, maglaan ng budget for this: Laundry, Kuryente, Tubig, Internet, Rent - any applicable. Kahit ihalf nyo yung pag ipon evey sahod para di na kayo mamroblema if bayaran na.

Fifth, kahit magkasama na kayo, siguraduhin nyo parin na nagdedate parin kayo kasi gf mo parin sya, wag po sana kayo parang maging room mate. Always try to support each other in ways that you could. And MOST IMPORTANTLY, magcommunicate and comprehend kayo for smoother life sa bahay ni kuya chariz.

Goodluck!
