How do I get out of a very bad dating rut!

For the most part, I have had good boyfriends over the last couple years. I broke it off with the first man due to him insisting that I move in—I was not ready at the time and I felt alot of stress from him and my family on the topic. About 6 mos later I met another man who I felt was worth committing to. The relationship was quite good, no major problems. I have a hard time when its my ‘time of month’ with my emotions and I started getting upset with him all the time. We had a bad outburst where he broke off plans with me on his birthday to stay home because he said he was working late ( through text message). I called him but he didnt my call. I decided to drive to his place and saw that he was not working and was there. I was so mad ( I had set up something for his bday) I walked into his apartment ( I had a key) uninvited and we had a horrible fight, I was crying and screaming, not my usual self at all. We broke up on the spot.
Its been a year since him and Ive been out on dates but I have not found any guy worth seeing. I dont meet many men because of the demand of my career and I am starting to feel very alone, my friends are all engaged or married. Overall, I do have my issues but all past boyfriends ( except for the last one) would say I am more normal than most girls. I dont drink/smoke, have a good job and am considered attractive by many men. Does anyone else feel this way? Has anyone else lost a good guy and regretted it like I do?? I am feeling like there is not much hope for me to find someone.
