Did I do the right thing & why do I feel so guilty?

My ex fiance of 1 mth. broke it off with no explanation why. We have been together for 7 yrs., 3 of them engaged. About 3 yrs. ago he basically did the same thing to me, broke it off out of the blue & hooked up with a married woman. This married woman just used him to get out of her divorce & 4 mth. later dumped him (Karma!). He shortly after came crawling back & 8 mths. later I made the decision to reunite with him because I loved him very much & he pulled no stops in convincing me that he had made a huge mistake & never stopped loving me & made promises that he would never hurt me like that again & then asked me to marry him. We then moved to his hometown & set up house. In the last 3 yrs. I have invested a lot to our home & intended on marrying soon. Well, as the story goes he once again for no good reason broke it off saying he needed his space. I of course new there had to be someone else on the scene & repeatedly asked him to be honest with me, which he denied continuously stating that he was not saying it was over for good, he just needed time to sort things out. I decided to give him his space with the hopes that he would decide he had made a mistake breaking it off with me but, I knew deep down there was another girl. He little by little started bringing some of my belongings to me as he lives an hr. away from where I live & still denied anything was going on. Today, something told me to take a drive out to his home & when I got there a vase filled with roses was on the table & next to it a note announcing a girls name with his last name at the end of it as if they were married & telling her that he loved her very much, how beautiful she is & he would see her later in the day. I don't need to tell you how I felt at that moment- even though I suspected it, I felt like someone had just punched me in the gut & my first reaction was to find him & rip him apart. Anger took over & I was like on auto pilot grabbing anything I had bought for us- all the curtains, bedding, you name it. I pretty much stripped the place of anything I could fit into my car & only things I had spent my own money on. There is still a lot more out there that I could not take with me (furniture). I did not call him nor have I heard from him but, I'm sure he got the message when he returned home & I'm hoping she was with him because just like the last time, I'm sure she has no clue I exist! Now I'm sitting here tonight & for some reason I'm feeling guilty for what I did because I'm really not a vindictive person & I can't just stop loving him just like that regardless, of how he feels & after all he has done to me. All he had to do is be honest with me- yes, I would of been devastated but, I wouldn't have been pinning away for him all mth. & hoping he would want me back & also, feeling like I had done something wrong to drive him away. Do you think I was right in what I did today & how can I stopped feeling so guilty? Should I not respond to any contact from him or what? Just 2 days before breaking it off with me, he was buying me flowers which he did often (it wasn't out of quilt-he can be quite the charmer) & telling me how much he loved me. What the hell is wrong with this guy- how can he just like that hook up with someone & start telling them how much he loves them when he is engaged to someone. How do you love a person in such a short time. Please, I would appreciate hearing what your thoughts are on what I should do- thank you.
