Need Advice

I’m so upset..My husband and I have been married for two years. Together for 10 in March. We are TTC and we waited 1.5 years to TTC because he said he wanted to have fun and be married. I agreed. Well this summer he said he was ready to start trying. And I feel like he puts no effort in at all. He works second shift and I get it’s rough but I feel like he doesn’t want it as badly as I do. And it hurts. I feel like anytime we fight it’s because we don’t have sex. I told him last night I’m close to ovulation. (I bought tests and all to start this journey.) He said..”Not tonight ..I’m really tired. We will tomorrow night I promise” and he just got up to go to bed. Completely “forgetting”..probably avoiding what he said. I’m not okay and I feel like it’s me. We barely have sex as it is because of our schedules..but why isn’t he giving effort. And I feel like when we do have sex..It’s not good..I don’t feel like he is physically there with me. I’m so sad...what do I do? Any advice? 🙁
