Feeling sad

So my hb and I decided to stop "preventing," which really means I'm trying. We have been talking about this for a few years now and this is the closest to "trying" he has ever come. We used the pull out method (sorry for tmi) for 5 years with no mishaps. Now we are on month two without it. Still no BFP. This week I got the news that 3 of our friends are preggers and it made me so sad, I almost cried in front of one of them. After work today I told him about our friend and he just said "good for them. " he didn't realize I was upset. Then for no reason I was sad and angry and cried to myself for like 20 min. I wish he understood how frustrating this is, but I don't want to pressure him, it's taken years to get this far. Any advice?
