ive been in a relationship with someone for 3 years and its almost perfect-- but when we fight its really bad. like so bad, i cant work or think... lately i've been thinking alot about an ex from like 10 years ago (even having dreams about him!). my ex has always been in my life; even though i moved away from him, we still talk and after years he finally has a seroius gf and i think im jealous! i think i always thought, no matter what, we'd end up together and have that fairy tale dream together. now with my current relationship crumbling and my "back up plan" unavailable i feel really alone. should i start looking for another?
