Am I distracted by love?

If he says he isn’t and doesn’t give you any reason to doubt him then I would guess he isn’t cheating. The fact that you feel jealousy might be a problem though if you don’t settle the issue. I would ask myself why I think he is cheating and try toi understand what exactly triggers your jealousy. The fact that he has friends athat are girls doesn’t count but if for example if he would rather spend time with them then you OR if they are only friends with him and not you OR if he spoends all his time with you tazlking to them…well these would all be things that could hurt your feelings and make you feel insecure. Once you’ve found what bothers you specificaly then you can talk about it and try to understand what solutions can be worked out.
