If you just spend a bit of time accumulating receipts/bills/evidence that these assets were yours before the marriage, then you be able to keep them. When I was married I sold my house (that I had purchased before married) and bought another. That house was joint property because it was purchased during marriage. So you have to consider things like that. But I had an investment coin collection before I was married and there was no question I got to keep it at the divorce. Of course I wasn't in time to keep my ex from stealing a coin from it. Start a joint account so you can keep your accounts separate. don't forget, any contributions to retirement accounts made during the marriage make it joint.
