I will offer the following advice, without any presumptions on your situation, but as some general benefits I have gained from my experiences and directed to myself more than anyone else.
Do not view past experiences as something bad - This can be difficult especially when even Muslims criminalize divorce. But what if each divorce was a mercy from Allah? Perhaps removing you from a relationship that would have later turned abusive or detrimental? We often develop trust issues in cases where we have been hurt - and to some degree that is natural in marriage and divorce, but try to think of those occurrences in terms of what Allah was trying to teach you (about yourself, this dunya, about Himself, etc.) Free your heart from any ill feelings over what happened or to the parties involved.
Put your trust in Allah - Even if we find someone who we feel can be trusted not to break the marriage bond with us, that is no guarantee we will stay married to them - they have no more control over their life than we do. Things like death, sickness, mental illness could all bring a marriage to an end. So refocus on marriage as a means to the pleasure of Allah and then put your trust in Allah that if you obey Allah, do your best and take all available means, then taking that step will bring you closer to Him (and insha'Allah result in a happy, health relationship).
Think about what practical lessons may be drawn from past experiences - think about signs that you possibly ignored, or steps you could have taken to make a more careful decision and then construct a 'pre marital interview process' that covers all of your bases. If someone meets all of those requirements then nagging doubts and whispers might just be Shaytaan trying to interfere with your forward progress. Pray istikhara and put your trust in Allah.
May Allah grant you a spouse from the most excellent of His servants. All good is from Allah. Please forgive me for anything I said that was the least bit offensive, presumptuous or inappropriate.
