I need some advice..

Abi
My husband and I have been trying to conceive for almost 7 months with no success. I can tell(here's for a shocker!!) that my always horny husband is less interested I. Sex then he ever has been. Most nights he comes to bed after I go to sleep it he sleeps on the couch... Do you know how I can make him more interested in me and not in getting me pregnant?
