Why just why????

Every month I get my hopes up thinking my hubby will be on board with making sure we have sex on certain days so we can try for baby making but he works a lot so I basically have to beg him. He told me I was trying to hard that you making it like a chore but how am I making sex like a chore when you wont even have sex with me on a regular basis. Just last night I asked him cause I didn't want to miss the fertile window I still have days but I want us to try harder this month but he's always tired I really feel like giving up. How can I ever have a baby if we don't have sex at all? This is ridiculous we've been married 5 years and no children together. He has a 20 year old and I have a 9 year old. He's 8 years older will be 42 next month and I am 33. I'm trying to just give me hopes and worries to Jesus. Keep my eyes on Him and trust Him. He knows best. But it's hard I mean if I gotta be 40 when I have a baby I guess that's okay. I've been feeling depressed about this whole situation life is short I just want to get pregnant at already ugh! God is in control just needed to vent!
