I'll always remember how the elders would go about telling the young about relationship issues and marriage. How they'll go saying that, tho years you've been in relationship with someone, it wouldn't be the same as how it is after marriage. Whether things go better or worst for both none will know.
My mom ever once told me, don't ever try to control your partner's activities, be it good or bad. Hear but don't believe what people are saying about your partner. Till unless he does the same to you, react. Tho some say it'll be too late, but I rather it be too late than never, I rather it'll be proven to me than regret. To trap a person it's not a wise solution.
To lie and pretend it's not either. My believe is to not say if you don't mean it. To not do if you don't like it. To not lie if you feel otherwise. My past decisions may did cause someone pain, but I believe up till now, it's the best solution. I've no clue if he's found someone better than me, but I hope he has, he will and just look behind as a brisk of memories. I do sometimes think of him, wish to see him and ask him of his well-being. Once I start to care for a person, I'll never stop, until of such circumstances.
What
Squadron said is right. One will always have memories of their past lives with whom it may concern. As long as memories remain memories, life should move on and peservere. But don't be mistaken, memories are not to say that one is still clingy to the past, but rather as a lifetime experience.
Right to this point of moment, whatever I've done in the past, I shall not regret. There's no use to it, rather just move on and find for the better. I smile to remember the people I came across in life, the people who made a change in me, who showed me priceless experiences and who has showered me with love once.
My future lies in the hands of the NoneOther.
