@april grace,
5 times in 3 months = about 1 meeting/18 days or so. Sex every time, including the first time, I assume, which is when you gave it up to him. During the 85 days (of 90 in three months) he didn't see you, he slept with another woman. He rarely contacts you. Now he says he wants to break up and see other people. He claims all will be wonderful and you will marry when you (not him) get a job. Such an interesting requirement.
You honestly think, once you get a job, he won't find some other reason to put off you riding off together into the sunset?
Be amenable to a break. A permanent one. He does not want to have anything with you. He is getting everything, everything, everything, and is giving you nearly nothing in return. At least he has the decency to call it quits but he does not have the decency or courage to stop stringing you along.
Get out of this now, and be happy you aren't married, as right now it's considerably easier for you to extricate yourself. I'm sorry, but it's over. But it never really started in the first place.
