Shame, guilt and depression

So im 25, just recently got married for the first time and we just found out we are pregnant.... But i recently fucked up just before we found out about the pregnancy. I was caught sexting another man. I know it was wrong and i know nothing justifies what i did but the reason i waa doing it was because it was exciting to hear what someone wants from you sexually and what theyd do. Ive tried getting my husband to sext with me but he always rejects the idea and says hes not good at it. Ive tried helping him out but he doesnt get into it. And its not like my husband isnt enough for me because hes all ive ever wanted... Ive wanted him since the 9th grade... Anyway we are trying to work through this together and i know its not going to just disappear from his mind but i feel like he hates me. And the fact that im pregnant im in crazy pain right now just getting used to the body changes so i dont want to have sex so he automatically takes it as im not attracted to him or i just dont want him or if its still going on with other guy(s) and i dont blame him in the slightest but it hurts me just as much and i dont think he sees that at all... Im not trying to play the pity game or anything i just really need to get this out somewhere and nobody in our lives know we are going through this hardship
