Where Did Love Go?

Hello, we have been together for a year and everything was wonderful, he showed me his love every day, he did not leave me, but everything changed after his mother did not approve of our relationship and started making scandals and problems for us ... he withdrew, he got colder, he disappeared, he didn't call or write to me .. it was like that for about 2 months, but things got better (not with his mother) .. we continued together and I felt his love again until one day .. in which he told me that we can now be together without a problem, BUT in front of his mother he is with another girl .. it struck me, I saw what comments and writes of the sort of-those eyes, beauty, in love, you are mine, etc ... I asked why they are needed and he said that he did not know what to write to her and that he would not tell her what he really wanted from her so as not to reach his mother. Okay, I resigned myself, but something has changed since last week ... see you, everything was fine as before, but he disappeared again .. he calls me during the day to ask me how I am and what I will do in the evening, but in the evening there is none, he comes in for 1 minute to read what I wrote to him and leaves, but I know he's sitting at the computer, he likes pictures, etc. and I see that, but he doesn't write to me. I don't know what to do anymore, should I give it up I wonder how you can love someone in one day and not in another ..
