Needing some advice.
Sorry it's a long one- please read!!
We are a youngish couple with a 1 year old and engaged to be married next year.
However the past 3-6 months i haven't felt 100% like I want this wedding.
Our relationship isn't as fun and loving as it ever was. We both work too so always tired and busy which doesn't help, but our sex life is awful and I dread what it would be like when we are married! 
He recently spoke to me about his low sex drive and doesn't know what to do or how to change it but the subject is so touchy I don't know what's best to do. It makes me feel so low then too because there doesn't feel like there's any love or emotion there at all!!
Mid wedding planning and I just can't help but think I'm doing the wrong thing but my heart is there??
Please help!!
