Yes I think it can but it's something that's going to take a whole lot of time. The thing with trust is that it has to be earned and when someone gives you their trust and you lose it then getting it back is difficult, but not impossible.

Whether or not you can regain a person's trust depends entirely on whether or not the person is willing to trust you again. If the person is willing to give it a try then it's very possible. Obviously it's going to take a much longer time than it took before but rest assured you'll get it back eventually.

My advice to anyone who's trying to regain the trust of a lover is to flee from anything and everything that might make them feel that you aren't trustworthy. If it's a password on your phone or a female/male friend who's a little too close, you have to get rid of them, at least until your partner trusts you again.

I hope this helps.
