Relationship help

I’ve been with my significant other for 13 years will be 14 this year… I’m not happy in my relationship… I dread going home after work.. i feel like my life is boring… I need excitement in my relationship… mind you he works for half the year then ends up collecting unemployment the other half and then ends up a stay home dad( does this every year).. I’m just tired and already explained what I want in life.. I think I wanna see other people
