Back to the drawing board

Last night wasnt the most fun of nights. Matt and I have an issue of communication. Together in the house, we basically do our own thing and take care of the boys semi-together. I usually deal with the boys more while Matt does what he wants. So, Ive mentioned earlier about the pornography I found on his computer. Well its an...every-time-i-leave issue now. I still havent said anything. I wanted to see if it was an isolated event. Its not, he now has about 10 or so websites saved on his computer. I have personal issues with porn. To each their own, but my marriage is not about that. We have talked about it before and he knows how i feel about it. So this isnt something that i feel thats just out of the blue. But back to last night. I was looking at some school stuff online and had facebook open. Matt was right near me and he noticed that I got a message from someone on facebook. He asked who i was talking to...so i asked him if he remember such and such. He said yeah....and I said he messaged me to see how I was doing. This was a guy that i "dated" in middle school. if you can even call it that. I havent talked to him since then. Happened that we had friends in common on facebook, so i messaged him and said long time no see...how have you been? This was days ago. He finally messaged me back last night and apoloigized for not writing back sooner and asked how i was. I told him that I lived in Missouri now, married and have two little boys. He told me about his wife and two little girls. We talked about Matt a lot and his career in the Army. then i had to go to get the boys ready for bed. When i told Matt who i was talking to, I told him what all we were talking about and he made the comment..."You arent going to start texting him are you?" I said, "No way, why would you even ask that?" He says because I did it last time that he doesnt want me to do it again. Now I know Im at fault for what he is talking about last time. But that was with one certain person. Not just every guy i know. Theres a difference. a big one. Well that comment ticked me off. I went to bed angry. Told him about it. He half apologized to me. If you can even call it an apology and he ended up falling asleep during the convo which ticked me off even more. I havent talked to him since. I dont know where all of this is headed now.
