Firstly go to confession and confess your apostasy so that you can be reconciled with God, until you do so you are in a state of mortal sin and should not receive the Eucharist as you are currently unworthy to do so.
Secondly never ever, ever betray Christ for any earthly man, Christ allowed Himself to be crucified for you, compared to Him Jason does not even come close.
Thirdly never ever again make the mistake of courting a non-Catholic,** the Church forbids mixed marriages for very good reasons**, reasons that effect the salvation of your soul. If you had went through with your plans and remained an apostate till your death you would have been spending eternity in hell.
Fourthly you need to take steps to strengthen your Faith, it is far to weak and means far to little to you if you could so easily abandon it.
If God wishes you to marry He will provide you with a suitable spouse when it is the right time, and God knows when that is better than you. If you would have a good Catholic husband then be a good Catholic Lady. If you do not know how to be a good Catholic Lady then I recommend you get a copy of “The Catholic Girls Guide” by Fr. F.X. Lasance which you can buy from here:
