husband help.

Alyssa
I got married in September 2016. I feel like my husband has become a different person since saying "I do". He is not affectionate towards me anymore, we rarely have sex, he's selfish with his time - picks the gym/football/his phone/basketball over me constantly.  Refuses to help keep our house clean. Blatantly ignores my requests for keeping the house cleaned up - such as no wet towels on the floor, wiping up toothpaste, dishes go in the sink, etc. nothing too complicated. He was definitely not like this before we got married - we even lived together for a year before hand. Am I crazy and just noticing these things now? How can I approach him to talk about this? I'm starting to feel worthless and unwanted. 😔
