Ranting!!!! Bringing out my pitchfork for a second

Jessizu • I wear lots of hats.
Ok so here is the situatuon.. Hubby travels for work and wasbin france from thr beginning of feburary to march 4th.. So i pick him up from thr airport and we have a wonderful dinner and then were back at the house and im doing his laundry and all is well... (He will work in the field from March 5th to 13th.. (13th is the last part of my fertile window)).. So then my dad calls me and said "hey i bought you a ticket you leave in the morning for your sisters house (in okc) becaise shes on the verge of a meltdown.." so no warning.. No talking about it... Ive had my husband back for all of 3 hours.. So i say ok as im concerned for my sis (oh yea i live in charlotte)... My husband is pissed.. He doesnt appreciate how my family just assumes my time.. So i said ok because hubby wouldnt be home this weekend but we would both be home for.next weekend (baby dancing! Yeah!!!).. So i get here to okc.... Sis is fine.... 11 month old niece is ..fine...... The house is dirty and so i guess she just needed a break.. So i went to dollar tree and grocery store.. Got stuff to clean around and organize a bit (thats all i did thursday and friday)... I get a call friday around noon and its my.hisband on his way home from work :,( i was so hesrt broken because now he says he will have to work through the following weekend (no baby dancing for my fertile window and im stuck way over here).... On top of that i have her 4 step kids here.. So im sleeping on the couch taking care of my niece so my sis can sleep and get the edge of this "breakdown" off... Wake up to the little rats fighting and swearing... Make them all breakfast... BIL and sis are still asleep and im trying to entertain these 5 kids that i hardly know.. All the while my hubby is giving me the silent treatment because he misses me too and doesnt know how to talk about those feelings and just clams up (hes introverted its fine)... But in the past 5 weeks ive seen my husband for 8 hours... And i wont see him for another 2 weeks.... Im feeling very lonely and taken advantage of... I feel like they just wanted a nanny for the weekend... I asked my sis if i could take a shower last night and she said "sure"... I said "can i have a towel" and she said "umm there might be some hanging up.. I dont know jjst look around"... Really?!?!?! I bust my balls cleaning and taking care of your kids (ive cooked all the meals and cleaned)..and you cant give me the decency to get me a towel so i can shower... Baby had a rough night so i was up with her most of thr night... Im fried... I cant tell my hubby this because he gets angry on my behalf.. I just needed to tell someone.... Im so sad.. Sad that i give everyone my all and i cant even get a freakin baby dancing weekend... :,(.. Starting to feel like i should just give up... Hubby and i have no kids.. I just quit my job as a preschool tea her because i couldnt make my RE appointments and my hubby got a raise so it wont hurt us financially... Just really bummed... Thoughs.. Coping mechanisms.....
