Melisa, your synasty with Fred actually looks really good. (Something I don't often say.) Unless their are some more serious problems with the relationship than what you've described (and drinking could be one,) I hope you can work things out.
Fred has a very strong 4th house-10th house axis. 4th meaning his family, and 10th meaning his career. These are areas of his life demanding his focus if he is to be at all true to himself. However, with your powerful Cancer yearning to belong to and blend with another person, and your possessive Scorpio moon, I can see why Fred's foci wouldn't sit well with you. The Saturn, opposite your sun, is always ready to feed into your feelings of insecurities.
With Pluto opposite his sun, plus a strong slug of Aquarius in his chart, Fred will have a perfect dislike or fear of being dominated by anybody.
Hence you can get into a dance of sorts, where the more you push, the more he pulls away. There's a lot I don't know about men, but processing a woman's anger and wanting to talk it through is generally not one of their skill sets. (You need a sympathetic girl friend for that kind of moral support.)
Getting angry at a guy who is in deep chill mode, is a sure way to drive him away even further. No, he won't want to talk about it. He will construe your efforts at logical discussion as your way of proving why you're right and he's wrong.
Your beautiful loving sun-Venus in Cancer is just now getting hit by the generational Pluto-Uranus square, forming a T-square with your sun-Venus. No doubt tensions have been building for a while. While this can be terribly trying emotionally, you can make the best use of it by learning to grow emotionally and breaking free of old habits that no longer support you.
Fred's Pisces planets have been hit by transiting Neptune, which can be a big time of confusion and low energy. If your relationship has been hitting a rough patch, right now he may simply be feeling demoralized and exhausted by it.
But these transits always pass, and hopefully we emerge as the "sadder but wiser girl" (and guy) from them.
