I need some advice
Okay so I was talking to my DH on the phone yesterday.  I told him that I was in rite aid to pick up some meds and a anniversary card for him. So I started reading a card and I said that I would call you back. So I was looking at card and I found two that I liked and some other things. I was thinking do I have enough to get them all. The two cards , meds and the other things I picked up? So I took my phone out my pocket and he was calling. He asked why I didn't answer my phone the first time he called? I told him that I didn't hear the phone ring. I looked the phone and it was on vibrate. It was online on vibrate because I took a pic and didn't want the ppl to hear the camera sound. He called me a lier and said that he wasn't going to our anniversary trip which we are leaving this morning. He thinks that I was seeing someone and I wasn't. He knows that I need my full attention when I pick out cards for me. 
I am so sad and confused. We are currently doing a <a href="https://glowing.com/glow-fertility-program">IUI</a> cycle and he is acting like this. TTC with PCOS is stressful enough for me and now this. ???
