I've been very lonely lately myself, and I really long for something meaningful. My point is, why let a good thing go? If she likes him and he likes her it is worth it at all costs to try to get back together. When we go through crisises in our life we find out who truly loves us. If she tells him what has been going on and just explains herself, her reasonings, and what has been going on in her life, I think he will understand and support her fully, and if he doesn't he is a no good shmuck!!!!!
