Confused

AmberDawn • just an Okie with 3 littles, & the best guy a gal could imagine!!!
Ok, so my husband is the most amazing man, he has always said that he does not want any children of his own (I have a 3 from previous relationship) with that being said we got married in January, I went to an OBGYN & disgusted BC & more permanent solutions & he freaked out on me, said i went behond his back, disrespected him, so i found this app & kept my mouth shut. I am always honest with him & I tell him & show him my phone when the app 'warns' me of ovulation & that we should avoid sex - so here is where I get real confused. ... he always 'slips' or needs to have before we can't have sex for a few days or hits me up right on the peak day or day after!? Which this thing might not be 100%!!! So now I wonder is he just a control freak or does he maybe have back ground issues I should keep in mind? Maybe of not be able to have children or fear of not being a good father ect? He did 9 years in the ARMY, Germany, Iraq & Japan before we found each other again & I think maybe there are things I don't know.... known since we were 14/15 now 30/31 married 5 mo together 19 mo
