Should i be feeling like this

Me and my boyfriend have now been together for a year and i still feel as though he wishes to be back with the mother of his kids that he was with for 13 years of his life i feel like i cant make him happy

he always does alot to keep her happy while all she does is take advantage of him and it gets me mad should i be feeling like this or should i not think this way i feel like the more i think about this the more it consumes me we constantly argue about this topic everyday
