Strings breaking in two weeks

So I’m not sure if it’s just because I’ve been practicing the let it be solo for a month straight trying to get it perfect but, twice in a row now my g has broke while bending after only two weeks of practicing maybe an hour a day. Is this an issue with my frets or is this just standard for strings? Sorry really just getting into bending so just wanted to make sure it wasn’t something that could just be a trivial fix. String just used to last like six months when just strumming/fingerpicking.
