Hello TSSM!
If you have only 2 days, we can’t help you. You can always try using our mones, the recommendations are excellent, mind you, but by the sound of it, you are looking for some magic potions and we are not selling any of that. 
Her having a bf, the fact that she entertained one, is a manifestation that her feelings towards you is dwindling. But it’s not the end of the world yet. Maybe it’s just a fling, a past time, an early stage of an attempt to find happiness because she can’t apparently find it with you.
And no amount of looking hunky and sexy will draw her back to you because the problem, as you mentioned earlier, is trust, and not attraction.
I seriously recommend a long, serious, adult, married couple heart to heart talk. And the recommended combo above may help the two of you clear things out.
Apologize, if you committed some errors. Be a man to accept responsibility and show her how sincere you are, both in your apology, and in your commitment to be THE Man of her and her family’s life. If the shedding of fat is one way of showing your sincerity, then its a plus.
I dropped the $25 Intro GC into your email earlier, and I hope it can help you, in case you have decided to heed the advice above and give it a shot, paired with the mones.
Remember, every success stories in this forum is a product of the tried and tested you+pheromone combo. 
Happy pheroing!
