Idk what else to do!!😔😢

My Fiance and I have been together for 11 yrs ingaged for a yr were both 30 now and over the yrs it's been full of rollercoasters, ups downs, ins and outs but of course when ur together that long what relationship don't have its flaws..ya know? Neither 1 of us is perfect and as much as we like to point fingers we both have things that could use a change to make our relationship better. We haven't had an arguement in over a month and now it's like for da last 3 days everything I say or do irritates the shit outta him (mind u he's only been bk from out of town for 5 days and leaving again in 25 days) I keep asking and basically begging for affection we've been TTC our 3rd child and it's like now I can't get him excited about being with me anymore. When I said this to him he says he just been irritated because he been sick with a cold since he got bk but not sick enough to not go over his friends house. I just don't know what to do anymore I'm trying to be patient and wait for him to realize how he's making me feel but damn I might a strong woman but I'm not Superwoman I still have feelings and emotions and I would love for the man I want to marry to take care these things with love and care it's sad because I love him to death but as my title said idk what else to do!!😔😔😔😔
