I agree with Zeph for the most part. However, I think that if he exchanged gifts along with cards, then that's just not right. Valentine's Day is the symbol of love, and to exchange more than a card with someone other than your mate, is proof of infidelity. From what you've said so far, you didn't even get a gift yourself, did you? Sounds shady to me. If he truly loved you, he would not have put you aside. Even with my biggest fights with my mate, we never cast the other one out, no matter what the fight was about. If he doesn't lose those feelings for his ex, then you two really shouldn't be together. Those who can't let go of the past should not try to move forward. Just tell him straight out. It's either you or the ex. It's as simple as that. I really hate people who are indecisive and taking advantage of people. Most of all, I hate those who delve in infidelity, it really pisses me off. Sorry, my advise morphed into my rant. but yea. It's you or the ex. One cannot have 2 worlds, only 1.
