Well we went out for seven months, (not long) but i loved him. And iw as really happy with him. And then randomly he broke up with me, a little more than a month ago, and then a few days after, he tells me he cheated on me. Im stuck on him, i still love him. But i wont take him back, cause i dont trust him. But geez, i wanna be over him!! HELP!!
