Will we work out? birthday is 12-13-1968 and mine is 04-28-1970.

Hi, my boyfriend and I reconnected after 30 years, we were young teenagers when we dated the first time around. This past January I looked him up as I had done several times in the past but this time I found him. After talking for a few months it was like the past 30 years apart hasn't existed and we fell in love again. His I am having issues with his brothers wife causing trouble because I'm the new girl in the family and I've been told she's jealous. Will she cause any more problems for us?
Thank you
