I need to get away from my pregnant girlfriend and daughter for a while?

My girlfriend is pregnant with our second daughter, 8 months along and she has been really angry and rude lately. It has stressed me out a lot. She has called me foul names and said she can';t believe I could have ever impregnated her. My daughter who is 5 is also being smart-aleck, begging for my attention the second I come in at the end of the day. my wife hasn;'t been making dinner so i've had to eat a lot of fast food lately abnd my daughter just complains about it and begs for stuff (dolls, toys, money, etc) I need a vacation from this for a while. where should i go? I was thinking Hawaii or Jamaica
