Your Man and Your Personality

First off, try to avoid landing in this situation. Your man IS YOUR MAN but it sounds like he may not be reciprocating the feelings. Ask yourself, does it feel like I am doing all the work? ...if you know what I mean?
Relationship starts, sparks fly, but for how long?. Someone new in your life makes you feel crazy things. I know, new partner and everyone in your past just doesn't seem to hold a candle stick to the new kid on the block. Sweaty palms, occasionally you fumble words, your just different--and that's okay. The way you feel is like a secret you want to keep and never share, it's just special. Something I have noticed is that I time passes quickly, and I am never tired.

When the magic stops, what is the cause? The feelings that once were are not what they used to be. But, if true love is there, the relationship will start its next phase, one of stability, comfort, and reliablity, the foundation to a long-term relationship.

Well as you come to see a more stable relationship, he is only interested in one thing. What can be done to make this a shared vision for the future. I'm afraid you won't like my answer, but a spark is not what you need to get him back forever. If you want him long-term you need a flame and both of you need to want that.
No matter how much you love him, you can't make him feel something he doesn't feel. If you are being true to yourself, this should not hit you out of left field. Today, out of nowhere, the conversation. You could almost feel it coming, like a car accident just before impact. This is terrible, you thought you shared something, possibly love.
Someone cannot be conditioned into love if it has not happened after you have tried your best. Today's the first day of moving on and finding your true love. ...If it's meant to be, fait will realign you both. Today's a day and tomorrow's a new. Look within, make your peace. But realize, he may have never loved you.
If you are still thinking of making this work STOP. If love becomes something he learns to pretned, your future is anything but bright. Resentment is inevitable. Disregard the unmistakable truth and prepare for a gut wrenching breakup sooner or later.
There's no getting around it, true love means a symbiosis of loving someone as is. Who wants to live in a play...acting won't cut it in real life.

It's time to be open, honest, and ask the same from him. You can still maintain a friendship. Then, let him go. He may return. Grab a tissue box and get him back forever. RomComs are great. Your girlfriends will be there for you. The right time and person will come along. You will find them. They may find you. But have faith and it all will work out in the end.

Let me know how it goes.
