Dry patch..

Hi all, my bf and I have been living together for 3 years and honestly.. I can tell we’re just comfortable, we’re barely affectionate. We both use to be extremely now it’s only when we’re going to have intercourse.. I can tell we’re both not into this as before. We have a child and I’m just scared this will get worse.. any ideas? How to bring spark back?

It’s hard because his hobbies is music, (he’s a dj) and basketball. Other than that he doesn’t watch any tv/ movies.. I’m trying my hardest to suggest something. We both gained a lot of weight I was going to suggest the gym together but his only day off is Sunday but he goes to play football with his friends.. and weekdays (we both work) but he’s constantly too tired when he gets home..

any thoughts welcomed
