My boyfriend is very ugly and poor, is he capable of cheating on me?

My boyfriend never remembers our anniversaries, but last week he gave me a present and when I asked why, he said that he just “wanted to make me happy”.

Then he drove me to a friend’s house and offered to pick me up later. That night, my mum called and said he’d gone to visit her and gave her a pot plant. He also asked her if she wanted him to take her shopping.
