Search Results: taking a break in a relationship boyfriend

Me and my boyfriend been together for around 7 months now. I have been hurt before by my ex and this created trust issues. I have been guarded up for first few months during our relationship but I have been opening up to him more. Yes we have been intimate for these past 2 months and it is going well. But I do have some doubts though I dont know if its just my insecurities taking over. I have been thinking about the following:
- he is quite fit and likes to take care of himself. I have let myself go for this past year so not motivated to go back to the gym. He has told me to come gym with him so now I feel insecure and thought about how maybe he wants a fit and better looking girl than me. I have told him this but he said "I want you to look after yourself but I still want to be with you" but I keep thinking Im not good enough for him and that he can find a better looking girl than me.
- Im not sure if its because of my birth control pills but I have been very moody at the moment and been quite depressed, keep thinking about how my life is unstable at the moment. Also, I keep thinking maybe Im not emotionally stable for a relationship. I do care and have strong feelings for my boyfriend but I kind of hate myself and I dont know if I can ever love someone if I dont love myself? Sometimes I doubt him when he says "i love you so much" but he has shown through his actions and efforts that he does care for me. When we had a massive argument, I was at a breaking point where I wanted to leave but he did fight for our relationship. I tend to give up on people easily and I know its not a good thing.
So I am confused. I dont know whether if these are good enough reasons to break up? Or maybe its just my insecurities? I care about him so much and I just don't want to hurt the both of us.
