Sometimes I feel like my boyfriend is too friendly and at times doesn’t respect my feelings I guess. So he’s friends with this female on social media and it seems like they flirting she recently blocked me . Then if I ask him to block somebody like a month later they end up unblocked and friends again. I want to walk away from the relationship because of these problems but I feel like I’ve invested too many feelings and to much time to walk away from this. We’ve been together almost 3 years
